I hate to tell you this, but Java actually does have a GOTO (not under that
name). It's a special form of "break" that can go to a defined label. See

The reason I hate to tell you this is because it is always a bad programming
idea.

Come on! If you are willing to consider this desperate measure to increase
execution speed, whay are you writing in Java in the first place?

So why not read about Java?
