Unecessary Code Detector (UCDetector) is an Eclipse plugin tool for pinpointing unnecessary public Java code, and suggests that you make the code final, protected, or private. It also locates cyclic dependencies between classes.

The latest release – version 1.6.0 – introduces support for searching for a class name in a file, and adds a new Rename mode button and a 'Log to Eclipse Console View' option. It also fixes bugs with missing QuickFix icons, malformed \uxxxx encoding in exception loading modes, and Headless failing to recognise projects.
