Given the code fragment:
Consider below code of Test.java file:
1. package com.sampleproject.oca;
2.
3. class Super {
4. public String num = "10"; //Line n1
5. }
6.
7. class Sub extends Super {
8. protected int num = 20; //Line n2
9. }
10.
11. public class Test {
12. public static void main(String[] args) {
13. Super obj = new Sub();
14. System.out.println(obj.num += 2); //Line n3
15. }
16. }
What will be the result of compiling and executing above code?
Given code of Test.java file:

8. void jump() { //Line n1
9. System.out.println("DEER JUMPS");
10. }
11.
12. void jump(int i) {
13. System.out.println("DEER JUMPS TO " + i + " FEET");
14. }
