Code Cleanup

[zzpprk]

All

I am maintaining some code and I have just seen something silly like the below. I corrected of course because we have an unused instance of class A floating around until the garbage collector decides to reclaim it.

A a = new A();
a = (A)...;

Do any of you know of a tool that can scan source code and detect such things?

Regards

That's the sort of thing Findbugs can look for.
There's a plugin for most, if not all, IDEs.

In most cases NetBeans does that.
