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 code of Test.java file: 

1. package com.udayan.ocp;

2.  

3. import java.util.stream.Stream;

4.  

5. public class Test {

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

7.         Stream stream = Stream.of("d", "cc", "bbb", "aaaa");

8.         stream.sorted().forEach(System.out::println);

9.     }

10. }

Which of the following needs to be done, so that output is:
