As a content-assisted hint, it is estimated that no one will use it, but it can also be used to do some quick input, such as the SYSTEM.OUT.PRINTLN () for beginners, as long as you enter the SYSO and then press the key combination to automatically complete and position the cursor in parentheses. In fact, some commonly used structures can be entered using this method, such as for, try ... catch and so on, as long as it is defined in the preference–java–editor–template can be used.

2, Ctrl + Shift + O
Quickly and automatically import the required packages.

3, Ctrl + D
Deletes the current line or selects the row.

4, Ctrl +/
Using a single-line comment annotation/uncomment the current line or select the row, the debugger inevitably has to temporarily close some code, so its usage is very high.

Practical and not frequently used edit shortcut keys
1, Ctrl + Shift + UP ARROW/down ARROW
Copy the current line or select the line to the previous line/next line of methods.

2, ALT + UP ARROW/down ARROW
Swap the current line with the previous line/next line and combine the previous set of shortcuts and you'll find it handy to copy and paste the code.

3, SHIFT + Enter/ctrl + SHIFT + Enter
Inserts a blank row on the next line/top line of the current line and moves the cursor to the newly inserted row.

Maximize/Cancel maximize the current window, when the code is relatively long to use it is very convenient, no need to switch the mouse double-click so troublesome.

1, Ctrl + K/ctrl + Shift + K

2, ALT + LEFT ARROW/ALT + RIGHT ARROW

3, Ctrl + Shift + T
Open the type and open the JDK class to see the source code.

4, Ctrl + Shift + G
You can see where the class, method, or property of the cursor is referenced, which is currently very small, because the code structure is simple, but it will be useful in the future.

Less-frequently-skilled shortcuts
1, Alt + Shift + S: Open the refactoring right-click menu, generate Getter/setter method, construct method, ToString () method
2 , Alt + Shift + Z: Put the selected code in a while, for, try...catch, etc structure
3, Ctrl + F6/ctrl + Shift + F6/ctrl + e switch to the previous/next editor or list the editor display card
4, F3 quickly locate the cursor position class, method, Properties
5, F4 display the current class inheritance relationship, and open the Class inheritance view (or similar Ctrl + T quickly show the current class inheritance)
