EXPERTY DESIGNED 1Z0-809 PRACTICE TEST

Given code of Test.java file: 

1. package com.udayan.ocp;

2.  

3. import java.util.*;

4.  

5. public class Test {

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

7.         NavigableMap map = new TreeMap<>();

8.         map.put(25, "Pune");

9.         map.put(32, "Mumbai");

10.         map.put(11, "Sri Nagar");

11.         map.put(39, "Chennai");

12.  

13.         System.out.println(map.headMap(25, true));

14.     }

15. }

Given code of Test.java file:

package com.udayan.ocp;

import java.util.Arrays;

import java.util.List;

public class Test {

    public static void main(String[] args) {

        List list = Arrays.asList("A", "E", "I", "O");

        list.add("U");

        list.forEach(System.out::print);

    }

}

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