To do this, we open Eclipse, select Window Style, and 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 on the team imported them into their own Eclipse.

Ctrl+D: Delete the current line
Ctrl+Alt+↓ Copy the current line to the next line (copy increase)
Ctrl+Alt+↑ Copy the current line Go to the previous line (copy and add)

Alt+↓ Interaction position between the current line and the next line (especially practical, you can save the need to cut and paste first)
Alt+↑ The current line and the interactive position of the previous line (same as above)
Alt+← Previous edited page
Alt+→ Next edit page (of course for the above one)

Alt+Enter Display 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 (this time The mouse can be anywhere in the current line, not necessarily the last)
Shift+Ctrl+Enter inserts a blank line in the current line (the principle is the same as the previous one)

Ctrl+Q locates the last edited place
Ctrl+L locates on a certain line (good news for those with more than 100 programs)
Ctrl+M maximizes the current Edit or View (press again and vice versa)
Ctrl+/ Comments the current line, presses again to uncomment
Ctrl+O Quick Display OutLine
Ctrl+T Quickly display the inheritance structure of the current class
Ctrl+W Close the current Editor

Ctrl+/(Keyboard) Collapse all codes in the current class

Ctrl+×(Keyboard) Expand all codes in the current class

Alt+/ instead)

Ctrl+Shift+E Display the manager that manages all currently opened Views (can choose to close, activate, etc.)

Ctrl+J Forward incremental search (press Ctrl After +J, each letter editor you enter provides quick matching to locate a word. If not

Ctrl+Shift+F Format the current code

,

and I like to sort out the ones I like and commonly use (Note: the shortcut keys for general refactoring all start

with )

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 Extract method (this is the most commonly used method in refactoring One of them, especially useful for a lot of mud code)

Alt+Shift+C Modify the function structure (more practical, there are N functions that call this method, modify it once)

Alt+Shift+L Extract local variables (you can Directly extract some magic numbers and strings into a variable, especially when multiple calls)

Alt+Shift+F Change the local variable in the Class into a field variable (a more practical function)

Alt+Shift+I Combine variables ( It may be a bit inappropriate to say that Inline)
Alt+Shift+V Move functions and variables (not very common)
Alt+Shift+Z Refactoring regret medicine (Undo)
