No input was found when learning Java, unlike python input and C scanf. I saw some exercises later.

Struct = new struct (System. in); int a = gradient. nextInt (); System. out. println ("input is" + a); struct. close ();

Eclipse shortcut

Most commonly used: Automatic completion: Alt +/Note: Ctrl +/new row: Shift + press ENTER cancel: Ctrl + z

 

Others are used for note-taking between me.

1. Import package: Ctrl + Shift + O

2. Alt + left and right direction keys
We often encounter situations where we read the code by pressing Ctrl + left-click, trace them layer by layer, and then get lost in the Code. In this case, we only need to press "Alt + Left-direction key" to return to the last read position, similarly, pressing "Alt + right arrow key" will move forward to the returned reading position, just like the browser's
The forward and backward buttons are the same.

3. shift + enter and ctrl + shift + enter
Shift + enter creates a blank row under the current row, regardless of whether the cursor is at the end of the row. Ctrl + shift + enter insert a blank row before the current row.

4. Press Ctrl + Shift + S to bring up the source menu

5. Ctrl + Shift + X change to uppercase Ctrl + Shift + Y decrease write

6. Cancel Ctrl + Z

7. Ctrl + Shift + C comments
