Add comments in Eclipse with a single keystroke

23 Sep

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.

Shortcut
Command Description
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.

    Hey there! I know this is kinda off topic but I was wondering if you knew where I could locate a captcha plugin for my comment form? I’m using the same blog platform as yours and I’m having difficulty finding one? Thanks a lot
