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
