Java program to sort map by its values

The java program to sort a map by its values are the program asked in the initial rounds of Java interview. Please find below code:

package test;

import java.util.*;

public class SortMapElementByValue {
    public static void main(String[] args) {
        Map<String, Integer> map = new HashMap<String, Integer>();
        map.put("Java", 82);
        map.put("C++", 40);
        map.put("Perl", 10);
        map.put("Groovy", 220);
        map.put("Html", 53);

        Set<Map.Entry<String, Integer>> set = map.entrySet();
        System.out.println(set);
        List<Map.Entry<String, Integer>> list = new  ArrayList<Map.Entry<String, Integer>>(set);

        Collections.sort(list, new Comparator<Map.Entry<String, Integer>>() {
            @Override
            public int compare(Map.Entry<String, Integer> o1,       Map.Entry<String, Integer> o2) {
                return o1.getValue().compareTo(o2.getValue());
            }
        });
        for (Map.Entry<String, Integer> entry: list) {
            System.out.println("Key: "+entry.getKey()+" Value:   "+entry.getValue());
        }
    }
}
