Why does Java allow for labeled breaks on arbitrary statements?

Question

I just learned today that the following Java code is perfectly legal:

myBlock: {
    /* ... code ... */

    if (doneExecutingThisBlock())
        break myBlock;         


        

Answer 1

The break statement terminates the labeled statement; it does not transfer the flow of control to the label. Control flow is transferred to the statement immediately following the labeled (terminated) statement.

It seems to be useful to exit nested loops. See http://download.oracle.com/javase/tutorial/java/nutsandbolts/branch.html

It's semantically the same as is there a equivalent of Java's labelled break in C# or a workaround
