confusing answer

[Rick Reumann]

I'm confused by this answer in JQ+ concerning labeled breaks:

A break statement with label Identifier attempts to transfer control to the enclosing labeled statement that has the same Identifier as its label; this statement, which is called the break target, then immediately completes normally. In this case, the break target need not be a while, do, for, or switch statement.
I'm not sure what they are saying here. I've used breaks in switches, and in loops but have never seen a break target not be a while, do, for, or switch statement with or without a label. Can someone show me an example of this? Or maybe I'm just totally missing what this quote is all about.
Thanks for the help.

Hey Rick..I am confused now..
Can any one clear our doubts? what does the statement is trying to say?..
I guess Rick is missing something..not sure.
Any Comments, Ranchers?.

It sounds like they are saying you could place a label anywhere in your program and break to it, although I can't seem to duplicate nor have I ever even seen it or heard of it before.

public class TestClass {
    public static void main(String asd[]){
        TestClass t = new TestClass();
        t.go();
    }
    void go() {
         
        //myLabel:  //my label works here
        for ( int i = 0; i < 7;i++ ) {
            if ( i == 3 ) {
                break myLabel;
            }
        }
            
        System.out.println("test 1");
        System.out.println("test 2");
        myLabel: //doesn't work here
        System.out.println("test 3");
    }
}

Hi
It means that you can use break without loops or switch. but when u are using it without loops or switch then u must give it label i.e.
{
// codes
break;
}
this will give compile error ... though it looks like it should come out of that block.
label01: {
// codes
break label01;
}
this will compile and works fine ..
