Find unused classes in a Java Eclipse project

Question

I have a large Eclipse project in which there exist several classes which, although they ceased to be used anywhere, were never marked @Deprecated.

How can I easily

Answer 1

Just use Analyze | Inspect Code with appropriate inspection enabled (Unused declaration under Declaration redundancy group).

Using IntelliJ 11 CE you can now "Analyze | Run Inspection by Name ... | Unused declaration"
