Java Program to retrieve the set of all values in HashMap

Java 8Object Oriented ProgrammingProgramming

First, create a HashMap and add elements −

HashMap hm = new HashMap();
hm.put("Wallet", new Integer(700));
hm.put("Belt", new Integer(600));
hm.put("Backpack", new Integer(1200));

Now, retrieve all the values −

Collection getValues = hm.values();
System.out.println("\nValues...");
Iterator i = getValues.iterator();
while (i.hasNext()) {
   System.out.println(i.next());
}

The following is an example to get the set of all the values in the HashMap −

Example

 Live Demo

import java.util.*;
public class Demo {
   public static void main(String args[]) {
      // Create hash map
      HashMap hm = new HashMap();
      hm.put("Wallet", new Integer(700));
      hm.put("Belt", new Integer(600));
      hm.put("Backpack", new Integer(1200));
      System.out.println("Map = "+hm);
      Collection getValues = hm.values();
      System.out.println("\nValues...");
      Iterator i = getValues.iterator();
      while (i.hasNext()) {
         System.out.println(i.next());
      }
   }
}

Output

Map = {Backpack=1200, Belt=600, Wallet=700}

Values...
1200
600
700
