Consider below code of Test.java file:

1. package com.sampleproject.oca;

2.  

3. public class Test {

4.     public static void main(String[] args) {

5.         String [][] arr = { {"%", "$$"}, {"***", "@@@@", "#####"}};

6.         for(String [] str : arr) {

7.             for(String s : str) {

8.                 System.out.println(s);

9.                 if(s.length() == 4) //Line n1

10.                     break; //Line n2

11.             }

12.             break; //Line n3

13.         }

14.     }

15. }

What will be the result of compiling and executing Test class?
