What will be the result of compiling and executing class M?
1. package com.udayan.ocp;
2.
3. class M {
4. private int num1 = 100;
5. class N {
6. private int num2 = 200;
7. }
8.
9. public static void main(String[] args) {
10. M outer = new M();
11. M.N inner = outer.new N();
12. System.out.println(outer.num1 + inner.num2);
13. }
14. }
Given the code fragment:
Consider the code of Greet.java file:
1. package com.udayan.ocp;
2.
3. public final class Greet {
4. private String msg;
5. public Greet(String msg) {
6. this.msg = msg;
7. }
8.
9. public String getMsg() {
10. return msg;
11. }
12.
13. public void setMsg(String msg) {
14. this.msg = msg;
15. }
16. }
Is Greet class an immutable class?
