You can only break to a label that is on a textually enclosing statement. In your example, the label is NOT on a statement that encloses the break
statement.
(For what it is worth, even higher-level languages that support goto
don’t allow you to jump into the middle of a loop from the outside. I’m thinking of C … and older languages like FORTRAN.)
Java allows you to break out, but breaking in is illegal … and will get you arrested 🙂
(Sorry, I couldn’t resist it. For those who don’t get the joke, a “break in” is when someone enters your house to steal stuff – see “break and enter” … )
