"goto" in Java

The only place a label is useful in Java is right before an iteration statement. And that means right before — it does no good to put any other statement between the label and the iteration. And the sole reason to put a label before an iteration is if you’re going to nest another iteration or a switch inside it. That’s because the break and continue keywords will normally interrupt only the current loop, but when used with a label, they’ll interrupt the loops up to where the label exists:

label1:
outer-iteration {
    inner-iteration {
        //...
        break; // (1)
        //...
        continue; // (2)
        //...
        continue label1; // (3)
        //...
        break label1; // (4)
    }
}

In (1), the break breaks out of the inner iteration and you end up in the outer iteration. In (2), the continue moves back to the beginning of the inner iteration. But in (3), the continue label1 breaks out of the inner iteration and the outer iteration, all the way back to label1. Then it does in fact continue the iteration, but starting at the outer iteration. In (4), the break label1 also breaks all the way out to label1, but it does not reenter the iteration. It actually does break out of both iterations.
