How to break out of nested for loops in Java

Answer 1

public class MyClass {
    public static void main(String args[]) {
        outer: for (int i = 0; i < 5; i++) {
            for (int j = 0; j < 5; j++) {
                if (i + j > 5) {
                    System.out.println("break");
                    System.out.println(i + " : " + j);
                    break outer;
                }
                System.out.println(i + " : " + j);
            }

        }
        System.out.println("end nested for loop");
    }
}
