How do I use the break statement?

By Wayan in Basic, Core API 0 Comment

The break statement has two forms, the unlabeled and labeled break. On the example below you see the first example as the unlabeled break. This type of break statement will terminate the innermost loop such as the for, while and do-while loop.

On the second example you’ll see the labeled break. We have two loops, the infinite while and the inner for loop. Using the labeled break we can terminate the outermost loop. In the for loop when the value of y equals to 5 then it will break to the start: label which will continue the program execution to the line after the while loop.

package org.kodejava.basic;

public class BreakDemo {
    public static void main(String[] args) {
        int[] numbers = {5, 3, 6, 9, 8, 7, 4, 2, 1, 10};

        int index;
        boolean found = false;

        int search = 7;
        for (index = 0; index < numbers.length; index++) {
            if (numbers[index] == search) {
                found = true;
                break;
            }
        }

        if (found) {
            System.out.println(search + " found at index " + index);
        } else {
            System.out.println(search + " was not found.");
        }

        start:
        while (true) {
            for (int y = 0; y < 10; y++) {
                System.out.print("y = " + y + "; ");
                if (y == 5) {
                    System.out.println();
                    break start;
                }
            }
        }
    }
}
