Shift+enter and Ctrl+shift+enter
Shift+enter creates a blank line below the current line, regardless of whether the cursor is at the end of the row. Ctrl+shift+enter inserts a blank line before the current line.
ALT + arrow key
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.
Ctrl+alt+↓ Copy the current row to the next row (copy increase) ctrl+alt+↑ Copy the current line to the previous row (copy increase) alt+↓ the current line and the following line interact (especially useful, you can save the first cut, then paste) alt+↑ the current row and the previous row interaction position (IBID.) Shift+enter inserts a blank row on the next line of the current row (at which point the mouse can be at any position in the current row, not necessarily the last)
