Victor,
There are some basic clean-up capabilities that you can find at Preferences > Java > Code Style > Clean Up – if you click Edit and go to the Unnecessary Code tab, you’ll have a better idea of what it can do.
There are plugins that can be installed into MyEclipse that will give you more advanced functionality:
1) Unnecessary Code Detector: https://marketplace.eclipse.org/content/unnecessary-code-detector
2) EclEmma Java Code Coverage: https://marketplace.eclipse.org/content/eclemma-java-code-coverage
Between those two plugins, I believe you will find the functionality you need. Do let us know if you need further assistance.
