eclipse text formatter

I have written some code in eclipse which has a lot of blank lines. I need to format the co开发者_StackOverflow社区de and remove the blank lines. How do I go about this?

You can use the default text formatter by selecting the code you want to format and then typing:

Ctrl + Shift + F (Contextual menu Source -> Format)

If this doesn't work you can edit this default formatter by changing the Existing blank lines - Number of empty lines to preserve from 1 to your number in Prefrences Java Code Style Formatter Edit Eclipse default formater Blank line tab.
