//Test.java

package com.udayan.ocp;

class Player {

    String name;

    int age;

    Player() {

        this.name = "Virat";

        this.age = 29;

    }

    public int hashCode() {

        return 100;

    }

}

public class Test {

    public static void main(String[] args) {

        System.out.println(new Player());

    }

}

Hexadecimal representation of 100 is 64.

Which of the following option is correct?

1. package com.udayan.ocp;

2.  

3. import java.util.Arrays;

4. import java.util.List;

5. import java.util.function.Predicate;

6.  

7. public class Test {

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

9.         List list = Arrays.asList(-80, 100, -40, 25, 200);

10.         Predicate predicate = num -> {

11.             int ctr = 1;

12.             boolean result = num > 0;

13.             System.out.print(ctr++ + ".");

14.             return result;

15.         };

16.         

17.         list.stream().filter(predicate).findFirst();

18.     }

19. }

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

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. }
