When you want to work with comments in Eclipse, you could use the slow way of moving to the start of the line, pressing // and then repeating this for all the lines you have.
Or you could use the quick way of adding a comment with a single keystroke no matter where the cursor’s positioned in the statement.
The same goes for Javadocs – there are just too many things to type before you can start commenting the good stuff. That’s why Eclipse also has a shortcut that let’s you add Javadoc to a field, method or class.
Keyboard shortcuts for comments and JavaDocs
Here are the keyboard shortcuts for manipulating comments.
|Ctrl+/||Toggle Comment||Add/remove line comments (//…) from the current line. The position of the cursor can be anywhere on the line. Works with multiple selected lines as well.Alternatively, you can also use Ctrl+Shift+C, which probably works better on a QWERTZ keyboard (eg. German layout), or Ctrl+7.|
|Ctrl+Shift+/||Add Block Comment||Wrap the selected lines in a block comment (/*… */).|
|Ctrl+Shift+\||Remove Block Comment||Remove a block comment (/*… */) surrounding the selected lines.|
|Alt+Shift+J||Add Javadoc Comment||Add a Javadoc comment to the active field/method/class. See the notes below for more details on where to position the cursor.|
