When i open any file in eclipse. it show alternative blank line after all the code lines and blank line. how can i remove it....
回答1:
In eclipse preference setting you can remove all the unwanted blank lines. Eclipse: Window > Preferences > Java > Code Style > Formatter > Edit the formatter and following screen will pop up.
And when you format the code all unwanted blank lines will be removed.
回答2:
Find: ^\s*\n
Replace with: (empty)
回答3:
Maybe you didn't understand what Anshu said. Do a Ctr-F on your editor. In the options, select Regular Expression. Enter ^\s*\n for the Find expression. Keep the Replace box empty. Replace All!
This of course might lead to removal of unwanted lines as well.
