Organize Imports in Eclipse
Today I learned a neat trick to organize imports in Eclipse. Of course, one can use Ctrl + Shift + O to remove the unused imports at file level. But what if you want to remove the unused imports for several files, may be at package level?
Simple – in the Package Explorer window, right click on the package that you want to modify and then select source -> Organize Imports which will analyse all the files inside that package and then remove the unused imports.
One more nifty trick is that you can automatically organize the imports when you save the file. To enable this, go to Windows -> Preferences -> Java -> Editor -> Save Actions and then enable Perform the selected action on save -> Organize imports. After this, whenever you save a java file, eclipse will remove the unused imports automatically.
