Write a Java program to get a collection view of the values contained in this map.

Sample Solution:-

Java Code:

import java.util.*;  
public class Example12 {  
     public static void main(String args[]){  
 
  HashMap<Integer,String> hash_map= new HashMap<Integer,String>();  
    hash_map.put(1,"Red");
  hash_map.put(2,"Green");
  hash_map.put(3,"Black");
  hash_map.put(4,"White");
  hash_map.put(5,"Blue");
       
   // checking collection view of the map
   System.out.println("Collection view is: "+ hash_map.values());
 }
}

Sample Output:

Collection view is: [Red, Green, Black, White, Blue]
