It is important for specific situations, like implementing your own collections, etc. In a standart case you should refrain from it. For more information read book "Effective Java" by Joshua Bloch. – ferrerverck Sep 15 '14 at 10:04

No, the garbage collector automatically detects local variables that are no longer used.

No. There is no need to. Local variables aka method variables which places on stack vanishes when we exit the local scope.
