Java Program to retrieve the set of all values in HashMap
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("
Values..."); 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
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("
Values..."); Iterator i = getValues.iterator(); while (i.hasNext()) { System.out.println(i.next()); } } }
Output
Map = {Backpack=1200, Belt=600, Wallet=700} Values... 1200 600 700
