Find all unused variable

Question

Normally it\'s easy to see unused variables in Netbeans, just a grey squiggly line.

But how would I find all of these unused variables in my project or of a single clas

Answer 1

The compiler will warn about unused variables giving you your list.

Unused method variables will be removed by the compiler but unused member variables remain, which depending on the state of your codebase may make this a cosmetic problem that can be handled as and when each file is modified rather than a conserted effort to remove all unused variables in one go.

Saying that, I generally like my builds to run with no warnings, so that when I genuinely break something I notice the warning. Maybe this is the clean-up you are looking for ;-)
