1you can delete it. if it generates an error undelete it. how can you detect if something is in use though? deprecation might be a better idea. – Logan Murphy May 16 '14 at 12:18

There exists a Eclipse plugin Unused Code Detector (http://www.ucdetector.org/). It can process a specific file or the entire project, searching for unused members/methods.

**UCDetector** does not detect the calls to methods from `.xml` files (in case of spring web-flow). So, it shows that the method is not being called from anywhere in the project, but ideally it is being called from web-flow. Is there any way where I can check the calls from web-flow as well apart from other `.java` files? – Nisarg Patil Feb 20 '18 at 14:28

2@NisargPatil Spring uses reflection to call these methods, there's no way a tool can detect that. Same applies to Struts. – Lluis Martinez Jun 19 '19 at 20:23

Ucdetector: You can install a plugin from this link. It works pretty well we have been using it in all our projects. It generates a html report as well it can mark warnings in eclipse. It helps you find unused classes, methods and variables. Only thing it dosen't do well is finding if a class is used via reflection only or where instance is created via spring. In these cases it still shows that class is unused.

Another thing you can do to clean up other types of unsed code is GoTo Window>Preferences>Java>Compiler>Error/Warnings
Now look for uncessary code section and tweak the settings as you desire to cleanup further.
I hope it helps :)
