Say you say: InputStream is = new InputStream(); //Object now exists is = new InputStream(); //The old object now gets deleted is = null; //The second object gets deleted There actually is no “free()”, when the Java VM detects that nobody can get it, then it collects it, but other than that, you can’t get it.

By just keeping a pointer, you prevent the address from being freed.

You mean Java will automatically delete your data if it thinks you are done with it? Good Lord Java sucks even more than I already thought! I'll decide when I want to delete something, thanks.
