Code labels in Java

Here you can find that at its initial phases Java provided the goto instruction. Wisely, this instruction is not longer implemented. Nevertheless, as I discovered few minutes ago in other SO question, labels do still exist.

int x;
letsassign: x = 3;

I wonder why they are still there. What other uses do labels have apart from goto label?

Solution

  • It is for sportly multiple loopings:

    outer: for (;;) {
    while (true) {
        if (brr) {
            break outer;
        }
    }
    roo();
}

    For break and continue.

    Java was designed to clean things up; after C++. However one did not want to risk outcries of "I cannot longer do that efficiently."
