Java Labels: A Simple Guide

What Are Java Labels?

 

Labels in Java are identifiers used to mark a specific point within code blocks.

When dealing with nested loops, labels help you control which loop you exit from or continue within. 

They work with break and continue statements to give you more control over your loops.

myLabel: // This is a label
for (int i = 0; i < 3; i++) {
    for (int j = 0; j < 3; j++) {
        if (j == 1) {
            break myLabel; // Exits the outer loop
        }
        System.out.println("i: " + i + ", j: " + j);
    }
}

Labels make your code clearer when you have complex loops. They let you exit or skip multiple loops at once, making your code easier to read and debug.

They offer better control over nested loops. Keep them in mind for those tricky scenarios.
