So example, we've declared an object,

Class object = new Class();

so how do you remove it ?

object = null;

doesn't help..

Objects are garbage collected in Java. Removing references to an object by setting variables = null will allow the GC to remove the objects sooner.

Thanks for reply.
So when we call object = null, so there's delay for removing object right?
I don't have to call GC right ?

No, you don't have to call the GC. objects are automatically garbage collected when there are no reachable references left.

This means that if you dont have to specify

object = null;

, because once the object goes out of scope it will be GC'd

I got an error

If you try to use a variable that has a null reference, you will get that Exception.
