Which of the following code segments, written inside main method will compile successfully?

Select 3 options.

package com.udayan.oca;

public class Test {

    public static void main(String[] args) {

        /*INSERT*/

        arr[1] = 5;

        arr[2] = 10;

        System.out.println("[" + arr[1] + ", " + arr[2] + "]"); //Line n1

    }

}

And below statements:

1. short arr [] = new short[2];

2. byte [] arr = new byte[10];

3. short [] arr; arr = new short[3];

4. short [2] arr;

5. short [3] arr;

6. int [] arr = new int[]{100, 100};

7. int [] arr = new int[]{0, 0, 0, 0};

8. short [] arr = {};

9. short [] arr = new short[2]{5, 10};

How many above statements can be used to replace /*INSERT*/, such that on execution, code will print [5, 10] on to the console?

1. package com.udayan.oca;

2.  

3. public class Test {

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

5.         StringBuilder sb = new StringBuilder();

6.         try {

7.             for(;;) {

8.                 sb.append("OCA");

9.             }

10.         } catch(Exception e) {

11.             System.out.println("Exception!!!");

12.         }

13.         System.out.println("Main ends!!!");

14.     }

15. }

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