I encountered a syntax I've never seen before:

A:switch(a)
    {
    case a1: 
        switch(b)
        {
        case b1:
            doB1();
            break; 
        default: 
            doDefault();
            break A;
        }
        // fall through
    case a2:
        doA2()
        break;
    }

The part that bugs me is the colon before switch in A:switch(...) and break A. Is there a name for this syntax? Where can I find documentation on this syntax?

It's a [labeled break](https://docs.oracle.com/javase/tutorial/java/nutsandbolts/branch.html) – Federico klez Culloca Apr 05 '18 at 15:37
