Given:

Which two statements are true? (Choose two.)

Given code:

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?

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

1. //Test.java

2. package com.udayan.oca;

3.  

4. class Point {

5.     static int x;

6.     private int y;

7.     

8.     public String toString() {

9.         return "Point(" + x + ", " + y + ")";

10.     }

11. }

12.  

13. public class Test {

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

15.         Point p1 = new Point();

16.         p1.x = 100;

17.         p1.y = 200;

18.         

19.         Point p2 = new Point();

20.         p2.x = 100;

21.         p2.y = 200;

22.         

23.         System.out.println(p1);

24.     }

25. }
