1. Open MyEclipse 6.0.1, then "window" → "Preferences" 2. Select "java", expand, "Editor", select "Content Assist". 3. Select "Content Assist", and then see the option "AutoActivation triggers for java" under "Auto-Activation" on the right and right. In fact, it refers to the symbol "." that triggers the code prompt. 4. For the option of "Auto Activation triggers for java", add abc after "." to facilitate the search and modification later. Then "apply" and click "OK". 5. Then, "File" → "Export", select "Perferences" in the pop-up window, and click "Next". 6. Select the export file path, export it to the desktop, enter "test" as the file name, and click "Save". 7. Find the file "test.epf" you just saved on the desktop, right-click and select "Open with Notepad". 8. You can see a lot of information about configuring MyEclipse 6.0.1. 9. Press the "ctrl + F" shortcut key, enter ".abc", and click "Find Next". 10. Find the configuration information of ".abc" as follows: 11. Change ".abc" to ".abcdefghijklmnopqrstuvwxyz(,", save and close "test.epf". 12. Go back to MyEclipse 6.0.1 interface, "File "→"Import", select "Perferences" in the pop-up window, click "Next", select the "test.epf" file that has just been modified, click "Open", and click "Finish". This step and the above The export steps are similar. 13. Finally, of course, code testing. Create a new project and create a new class. Enter switch, foreach, etc. in the code to test. You will immediately find that there is a prompt, and no matter which letter is typed, it will be There are a lot of related tips, very smooth and convenient. Summary: The option "Auto Activation triggers for java" refers to the option that triggers the code prompt. Change the "." to ".abcdefghijklmnopqrstuvwxyz(," to mean 26 letters and ., (these symbols trigger the code prompt Function. By the way, modify the class name, interface name, etc. to be highlighted in different colors, you can configure it in "java"→"enditor"→"syntac", expand "java"→"classes" on the right, and check " "Enable" option, just choose the color you like. Of course, there are other related color configurations. I won’t talk about the specifics. In fact, there are many things that can be configured in the "Preferences" item, which makes MyEclipse optimized. It is necessary for each person to configure according to their personal preferences.
The editing function of Eclipse is very powerful. Mastering the Eclipse shortcut key function can greatly improve development efficiency. There are some shortcut keys related to editing in Eclipse. 1. [ALT+/] This shortcut key is a good helper for users to edit, and can provide users with content assistance. Don't worry about memorizing the names of methods and properties. When you fail to memorize the names of classes, methods and properties, please experience it more [ ALT+/] shortcut keys bring the benefits. 2. [Ctrl+O] Display the outline of the methods and properties in the class, which can quickly locate the methods and properties of the class, which is very useful when looking for bugs. 3. [Ctrl+/] Quickly add comments, you can quickly add or uncomment the line where the cursor is located or the selected line, you may always need to comment or uncomment something when debugging, now it’s fine, no need for each line Make repeated notes. 4. [Ctrl+D] Delete the current line, which is also one of the author's favorites. There is no need to press the delete key so many times to delete a line. 5. [Ctrl+M] The window is maximized and restored. When users operate in the window, they will always feel that the current window is small (especially when writing code). Now it's fine, try the [Ctrl+M] shortcut. Viewing and locating shortcut keys In the program, it is very difficult to quickly locate the location of the code and quickly find the location of the bug. Eclipse provides a powerful search function. You can use the following shortcut keys to help you complete the search and location work. 1. [Ctrl+K], [Ctrl++Shift+K] Quickly find the selected content down and up, no longer need to click the find dialog box with the mouse. 2. [Ctrl+Shift+T] Find the Java class files that can be found in the Workspace build path. Don't worry about not finding the class, and you can use wildcards such as "*" and "?". 3. [Ctrl+Shift+R] corresponds to [Ctrl+Shift+T], find all files (including Java files) in the workspace (Workspace), you can also use wildcards. 4. [Ctrl+Shift+G] Find references to classes, methods and attributes. This is a very useful shortcut key. For example, if you want to modify the code that references a certain method, you can quickly locate all references to this method by pressing the shortcut key [Ctrl+Shift+G]. 5. [Ctrl+Shift+O] Quickly generate import. After copying a program from the Internet, I don’t know how to import the called class. Try the [Ctrl+Shift+O] shortcut, and you will be pleasantly surprised. 6. [Ctrl+Shift+F] Formatting code, writing standardized code is a compulsory course for every programmer. When you see a certain piece of code that is extremely unpleasant, press [Ctrl+Shift+F] to make a shortcut after selecting it. The key can format this code, if the code is not selected, the current file (Java file) will be formatted by default. 7. [ALT+Shift+W] Find the path in the project where the current file is located, you can quickly locate the location of the browser view, if you want to find the package where a file is located, this shortcut key is very useful (especially in larger projects) in). 8. [Ctrl+L] Navigate to a certain line of the current editor, which is also valid for non-Java files. 9. [Alt+←], [Alt+→] Backward history and forward history are very useful when tracking code. Users may find several related places, but they may not remember clearly. You can use these two shortcuts Key locates the order of search. 10. [F3] Quickly locate a certain class, method and attribute at the cursor position. 11. [F4] Display the inheritance relationship of the class, and open the class inheritance view. 【F3】Quickly locate a certain class, method and attribute at the cursor position. 11. [F4] Display the inheritance relationship of the class, and open the class inheritance view. 【F3】Quickly locate a certain class, method and attribute at the cursor position. 11. [F4] Display the inheritance relationship of the class, and open the class inheritance view.
There are some shortcut keys related to running and debugging in Eclipse. 1. [Ctrl+Shift+B]: Set a breakpoint or cancel the set breakpoint in the current line. 2. [F11]: Debug the last executed program. 3. [Ctrl+F11]: Run the last executed program. 4. [F5]: Trace to the method, when the program executes to a method, you can press the [F5] key to trace to the method. 5. 【F6】: Single-step execution of the program. 6. [F7]: After executing the method, return to the next statement that called the method. 7. [F8]: Continue to execute until the next breakpoint or the end of the program.
Usually text editors provide some editing-related shortcut keys, and you can also use these shortcut keys for text editing in Eclipse. 1. [Ctrl+C]: Copy. 2. [Ctrl+X]: Cut. 3. [Ctrl+V]: Paste. 4. [Ctrl+S]: Save the file. 5. [Ctrl+Z]: Cancel. 6. [Ctrl+Y]: Repeat. 7. [Ctrl+F]: Search.
There are many shortcut keys in Eclipse, which cannot be listed one by one. Users can find out how to use them through the help document. In addition, there are several commonly used shortcut keys as follows. 1. [Ctrl+F6]: Switch to the next editor. 2. [Ctrl+Shift+F6]: Switch to the previous editor. 3. [Ctrl+F7]: Switch to the next view. 4. [Ctrl+Shift+F7]: Switch to the previous view. 5. [Ctrl+F8]: Switch to the next perspective view. 6. [Ctrl+Shift+F8]: Switch to the previous perspective.
There are many shortcut keys in Eclipse. You can find the use of all shortcut keys through the help document, but it is impossible and unnecessary to master the use of all shortcut keys.

This article is a summary of some of the most practical, complete, and time-saving Eclipse shortcut keys. These shortcut keys can help you complete any operation in your work. Welcome reference.
This may be the most time-saving of all shortcut key combinations. This set of shortcut keys allows you to open any file in your workspace, and you only need to press the first few letters of the file name or mask name, such as applic*.xml. The fly in the ointment is that this set of shortcut keys is not available in all views.
If you want to view the methods of the current class or a specific method, but don't want to pull up and down the code, and don't want to use the search function, just use ctrl+o. It can list all methods and attributes in the current class. You only need to enter the name of the method you want to query, and click enter to jump directly to where you want to go.
This set of shortcut keys will help you navigate between open editors. Use ctrl+page down or ctrl+page up to browse the front and back tabs, but when many files are open, ctrl+e will be more efficient.
In the development process, I often write a method first, such as Calendar.getInstance(), and then assign the calculation result of the method to a local variable through the ctrl+2 shortcut key. This saves me the time to enter class names, variable names, and import declarations. The effect of Ctrl+F is similar, but the effect is to assign the calculation result of the method to the domain in the class.
Renaming properties and methods was a cumbersome task a few years ago, requiring a lot of search and replacement, so that the code became fragmented. Today's Java IDE provides source code processing functions, as does Eclipse. Now, the renaming of variables and methods is very easy, and you will be used to renaming them every time a better alternative name appears. To use this function, move the mouse to the attribute name or method name, press alt+shift+r, enter the new name and click Enter. That's it. If you are renaming an attribute in the class, you can click alt+shift+r twice, which will call out the source code processing dialog box, which can realize the automatic renaming of the get and set methods.
Source code processing also includes the function of extracting variables and methods from large blocks of code. For example, to create a constant from a string, just select the text and press alt+shift+l. If the same string appears elsewhere in the same category, it will be automatically replaced. Method extraction is also a very convenient function. Breaking large methods into smaller, well-defined methods will greatly reduce complexity and improve the testability of the code.
Shift+enter creates a blank line below the current line, regardless of whether the cursor is at the end of the line. Ctrl+shift+enter inserts a blank line before the current line.
This is also a magic weapon to save time. This combination moves the content of the current line up or down. In the try/catch section, this shortcut is especially useful.
Everyone knows that large display screens can improve work efficiency. Ctrl+m is the shortcut key for maximizing the editor window.
ctrl+. Move the cursor to the next error or warning in the current file. I usually use this set of shortcut keys together with ctrl+1 to modify the suggested shortcut keys. The modification suggestions of the new version of Eclipse are very good and can help you solve many problems, such as missing parameters in methods, throw/catch exceptions, unexecuted methods, and so on.
More shortcut key combinations can be viewed in Eclipse by pressing ctrl+shift+L.
Let's take a look at some of my favorite hotkey combinations according to the frequency of use. (Note: The following content has passed the test in Eclipse3.02 and the first version)
1. Control-Shift-T: Open type. If you are not deliberately working hard, forget to open it through the source tree. It is easy to open the implementation class of the interface with eclipse. Press ctrl+t to list the implementation class list of the interface
2. Control-Shift-R: Open resources (not just to find Java files). Tip: Use the yellow two-way arrow button in the Navigator view to associate your editing window with the navigator. This will allow the files you open to be displayed in the hierarchical structure of the navigator, which makes it easier to organize information. If this affects speed, turn it off.
3. F3: Open declaration. Or, use the Declaration Tab (in Java view mode, select Windows -> Show View -> Declaration). When you select a method in the code and press this button, it will display the entire method in the declaration box.
4. Alt-left arrow: Go back in the Navigation History.Just like the back button of a web browser, it is especially useful after using F3 to jump. (Used to return to the original compiled place)
5. Alt-right arrow: Move forward in the navigation history.
6. Control-Q: Go back to the last edited place. This shortcut is also used when you jump in the code. Especially when you drill too deep and forget what you were doing in the first place.
7. Control-Shift-G: Search for references in the workspace. This is the prerequisite for refactoring. For methods, the function of this hotkey is exactly the opposite of F3. It allows you to find all the callers of a method up in the method stack. A related function is to turn on the "marking" function (occurrence marking). Select Windows->Preferences->Java-> Editor-> Mark Occurrences and check the option. At this time, when you click on an element, all the places where the element exists in the code will be highlighted. Personally, I only use "Mark Local Variables" (Mark Local Variables). Note: Too many highlighting will slow down Eclipse.
8. Control-Shift-F: CodeàJavaàPreferencesà to reformat the code according to the code style setting. Our team has a unified code format, and we put it on our wiki. To do this, we open Eclipse, select Window Style, and then set Code Formatter, Code Style and Organize Imports. Use the Export function to generate configuration files. We put these configuration files on the wiki, and then everyone in the team imported into their own Eclipse.
9. Control-O: Quick outline. With this shortcut key, you can quickly jump to a method or attribute, and you only need to enter the first few letters of the name.
10. Control-/: Comment or uncomment a line. The same applies to multiple rows.
11. Control-Alt-down arrow: Copy the highlighted line or lines.
12. Alt-down arrow: Move one or more rows down. Alt-up arrow will move up.
Other hot keys are available in the menu. You can see a list of all shortcut keys by pressing Control-Shift-L (from version 3.1). Press Control-Shift-L twice to display the Keys Preferences dialog, where you can set the hotkey yourself. I welcome you to post your Eclipse tips in the Talkback section.
I summarized a few related tips:
Lock the command line window : In the command line view (Window ->Show View ->Other ->Basic ->Console), try using the scroll lock button to lock the console output without scrolling.
Use the Ant view : In my Java or Debug mode, I like to show the Ant view so that I can run Ant tasks quickly. This view can be found through Window Ant. Put the Ant view in the corner of the screen and add the build.xml file through the "Add à Other à Show View à Buildfiles" button. In version 3.1, even the Ant debugging scripting language is supported.
Automatically traverse a collection : for + Control-Space: If you don’t know yet, then you should remember that Control-Space is an auto-completion function. In Eclipse, you can also auto-complete the structure. Within an array or collection, try typing "for" and then pressing the Control-Space key. Eclipse will ask you which collection you want to traverse and then automatically complete the loop code.
Use hierarchical layout : The default layout (flat style) in the Package Explorer view confuses me. It displays the full name of the package in the navigation tree. I prefer the package and file system view of my source code, which is called Hierarchical Layout in Eclipse. To switch to this mode, click the down button in the package browse view, select Layout, and then select Hierarchial.
Show multiple files at once : You can browse multiple files at once. Drag the edit window that is not in the active state to the scroll bar at the bottom or side of the active window to open the edit window. This is the best way I can describe the trick.
Open two Eclipses at the same time : To merge changes from one CVS branch to another, I like to do so by opening two working directories (Workspace) with different Eclipses at the same time. This way I can see all the changes by comparing the latest version on CVS (right-click on the project, and select Compare Lastest from HEAD) and merge each change into another CVS branch. The easiest way to start multiple Eclipses is to use Eclipseàwith Launcher.
Implementors plug-in : Install a plug-in that can jump to the implementation of an interface. If you are a dependency injection fan, or are working based on well-written interfaces, then you need a plugin like this to speed up code navigation. You can find this plugin at SourceForge.
If you want to know which methods of a class are called by other classes, please select the method name and press "Ctrl+Alt+H",
Eclipse will show which methods this method is called, and finally generate a call relationship tree.
1. Ctrl+Left Button
This is often used by most people to view the definitions of variables, methods, and classes
View the outline of a class, listing its methods and member variables. Tip: Press Ctrl+O again to list the inherited methods and variables of this class.
View the inheritance tree of a class, it is top-down, press Ctrl+T again, it will change to the bottom-up display structure.
Tip: Select a method name and press Ctrl+T to view the parent class, subclass, and interface of the method with the same name.
Mnemonic: "T"——->"Tree" —–>"Hierarchical Tree"
4.Alt+left and right arrow keys
We often encounter the situation of Ctrl+Left button, tracking layer by layer when looking at the code, and then getting lost in the code. At this time, you only need to press "Alt+Left arrow key" to return to the last reading position. Similarly, press " "Alt+Right Arrow" will advance to the reading position you just went back to, just like the browser’s forward and back buttons.

(8) Alt+Shift+O (or click the Toggle Mark Occurrences button in the toolbar) When you click a mark, the mark in other places on this page will be highlighted in yellow, and a white square will appear on the right border of the window. Clicking on this box will jump to this mark.
(9) Right-click the left border of the window, which is the place where the breakpoint is added, and select Show Line Numbers to add line numbers.
(10) Ctrl+I Format Active Elements. Ctrl+Shift+F Format Document.
(11) Ctrl+S saves the current file. Ctrl+Shift+S saves all unsaved files.
(12) Ctrl+Shift+M (first put the cursor on the class name of the package to be imported) The function is to add the Import statement. The effect of Ctrl+Shift+O is that the missing Import statement is added, and the redundant Import statement is deleted.
(13) Ctrl+Space prompts that the content to be typed is Content Assist. At this time, the shortcut keys of Chinese (Simplified) IME-Ime/Nonlme Toggle (used to switch between English and other text) in the input method should be changed to other. Ctrl+Shift+Space prompt information is Context Information.
(14) Double-click the left border of the window to add a breakpoint.
(15) Ctrl+D deletes the current line.
Eclipse shortcut keys
Ctrl+1 quick fix (the most classic shortcut key, needless to say)
Ctrl+D: delete the current line
Ctrl+Alt+↓ Copy the current line to the next line (copy increase)
Ctrl+Alt+↑ Copy the current line to the previous line (copy increase)
Alt+↓ The interactive position of the current line and the next line (especially practical, you can save the cutting and then pasting)
Alt+↑ The interactive position of the current line and the upper line (same as above)
Alt+← the previous edited page
Alt+→ the next edited page (of course for the above one)
Alt+Enter displays the properties of the currently selected resource (project, or file or file)
Shift+Enter insert a blank line in the next line of the current line (the mouse can be at any position of the current line at this time, not necessarily the last)
Shift+Ctrl+Enter insert a blank line in the current line (the principle is the same as the previous one)
Ctrl+Q Position to the last edited place
Ctrl+L is positioned in a certain line (for those with more than 100 programs, there is a gospel)
Ctrl+M Maximize the current Edit or View (press again to vice versa)
Ctrl+/comment the current line, press again to cancel the comment
Ctrl+O quickly display OutLine
Ctrl+T quickly display the inheritance structure of the current class
Ctrl+W close the current Editor
Ctrl+K Quickly locate to the next one with reference to the selected Word
Ctrl+E quickly display the drop-down list of the current Editor (if the current page is not displayed, it is indicated in bold)
Ctrl+/(small keyboard) collapse all codes in the current class
Ctrl+× (keyboard) Expand all codes in the current class
Ctrl+Space code assistant completes the insertion of some codes (but generally conflicts with the input method, you can modify the hotkey of the input method, or you can temporarily use Alt+/instead)
Ctrl+Shift+E displays the manager that manages all the currently opened Views (you can choose to close, activate, etc.)
Ctrl+J Forward incremental search (after pressing Ctrl+J, the editor for each letter you enter provides quick matching to locate a certain word, if not, it will display in the stutes line that it is not found, check one It is particularly useful when it comes to words. This feature Idea had two years ago)
Ctrl+Shift+J reverse incremental search (same as the previous one, but search from back to front)
Ctrl+Shift+F4 Close all open Editors
Ctrl+Shift+X change the flavor of the currently selected text to lowercase
Ctrl+Shift+Y changes the currently selected text to all lowercase
Ctrl+Shift+F format the current code
Ctrl+Shift+P Position to the matching character (such as ()) (When positioning from the front to the back, the cursor should be in the matching character, from the back to the front, and vice versa)
The following shortcut keys are commonly used in refactoring, and I like to organize them frequently (Note: Generally, the shortcut keys for reconstruction start with Alt+Shift)
Alt+Shift+R Rename (it is my favorite one, especially the Rename of variables and classes, which can save a lot of labor than manual methods)
Alt+Shift+M extraction method (this is one of the most commonly used methods in refactoring, especially useful for a lot of mud code)
Alt+Shift+C modify the function structure (more practical, there are N functions called this method, modify it once)
Alt+Shift+L extract local variables (you can directly extract some magic numbers and strings into one variable, especially when called in multiple places)
Alt+Shift+F turns the local variable in Class into a field variable (a more practical function)
Alt+Shift+I merge variables (it may be a bit wrong to say that Inline)
Alt+Shift+V Move functions and variables (not very commonly used)
Alt+Shift+Z refactoring regret medicine (Undo)
