1. Ctrl+space: Auto-complete function

Code helper to complete some code insertion (but general and input method conflicts, you can modify the input method hotkey, you can also take up

2. F3: Open Declaration

Alternatively, use Declaration Tab (in Java view mode, choose Windows--Show View-> Declaration). When you select a method in the code and press the button, it will show the entire method in the Declaration box.

3. CONTROL-SHIFT-G: Searching for references in workspace (reference)

This is the premise of refactoring. For the method, the function of this hotkey is exactly the opposite of F3. It enables you to find all the callers of a method in the stack of methods. One function associated with this is to turn on the "tagging" feature (occurrence marking). Select windows->preferences->java-> editor-> Mark occurrences and tick the option. At this point, when you click on an element, all of the elements in the code where the element exists will be highlighted. I personally only use "Mark local variables" (Mark locally Variables). Note: Too much highlighting slows eclipse.

4. Control-alt+h

If you want to know how a class's methods are called by those other classes, check the name of the method and press "Ctrl+alt+h".

4. control-/: Comment on a line or uncomment it. Same for multiple lines

5. Ctrl+shift+r: Open Resource

This is probably the most time-saving combination of all shortcut keys. This set of shortcuts lets you 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 drawback is that this set of shortcuts is not available in all views.

6. Ctrl+o: Fast Outline

If you want to see the methods of the current class or a particular method, but do not want to pull the code down, and do not want to use the search function, then use Ctrl+o bar. It can list all the methods and properties in the current class, you just enter the method name you want to query, and click Enter to jump directly to where you want to go.

7. Ctrl+e: Quick Convert editor

This set of shortcut keys will help you navigate between the open editors. Use ctrl+page down or ctrl+page up to browse the tabs before and after, but ctrl+e is more efficient when many files are open.

8.alt+shift+r : Rename

Renaming properties and methods was a hassle a few years ago, requiring a lot of searching and replacing so that the code became fragmented. Today's Java IDE provides source-processing functionality, as is eclipse. Now, the renaming of variables and methods is very simple, and you'll get used to renaming each time a better alternative name appears. To use this feature, move the mouse over the property name or method name, press Alt+shift+r, enter a new name, and then click Enter. This is done. If you rename a property in the class, you can click Alt+shift+r two times, this will call out the Source Processing dialog box, you can implement the get and set method of automatic renaming.

9. Alt+shift+l and alt+shift+m: Extracting local variables and methods

Source processing also includes the ability to extract variables and methods from chunks of code. For example, to create a constant from a string, select the text and press Alt+shift+l. If the same string appears elsewhere in the same class, it is automatically replaced. The method extraction is also a very convenient function. Breaking up large methods into smaller, well-defined methods can greatly reduce complexity and improve the testability of your code.

ALT + arrow keys

This is also a magic weapon to save time. This combination moves the contents of the current line up or down. In the Try/catch section, this shortcut is especially useful.

Ctrl +. and ctrl+1: Next error and quick change

CTRL +. Moves the cursor to the next report fault or warning in the current file. This set of shortcut keys I generally use with ctrl+1, that is, modify the proposed shortcut keys. The new version of Eclipse suggestions are good to help you solve a lot of problems, such as missing parameters in the method, Throw/catch exception, non-executed methods and so on.

The above is just a summary of some, commonly used shortcut keys, here are some detailed links:
