Given the code fragment:

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

1. package com.udayan.oca;

2.  

3. public class Test {

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

5.          int x = 1;

6.          while(checkAndIncrement(x)) {

7.              System.out.println(x);

8.          }

9.      }

10.  

11.      private static boolean checkAndIncrement(int x) {

12.          if(x < 5) {

13.              x++;

14.              return true;

15.          } else {

16.              return false;

17.          }

18.      }

19. }

Given:

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?

Given code of Thought.java file:

1. public class Thought {

2.     /*INSERT*/ {

3.         System.out.println("All is well");

4.     }

5. }

Which 3 options, if used to replace /*INSERT*/, will compile successfully and on execution will print "All is well" on to the console?
