Syntax error Get the set of values in Java IdentityHashMap

Get the set of values in Java IdentityHashMap

To get the set of values in IdentityHashMap, use the values() method.

First, set the IdentityHashMap

Map<String, Integer> m = new IdentityHashMap<String, Integer>();
m.put("1", 100);
m.put("2", 200);
m.put("3", 300);
m.put("4", 150);
m.put("5", 110);
m.put("6", 50);
m.put("7", 90);
m.put("8", 250);
m.put("9", 350);
m.put("10", 450);

Now, retrieve the set of values

m.values()

The following is an example to get the set of values in IdentityHashMap using values() method

Example

 Live Demo

import java.util.*;
public class Demo {
   public static void main(String[] args) {
      Map<String, Integer> m = newIdentityHashMap<String, Integer>();
      m.put("1", 100);
      m.put("2", 200);
      m.put("3", 300);
      m.put("4", 150);
      m.put("5", 110);
      m.put("6", 50);
      m.put("7", 90);
      m.put("8", 250);
      m.put("9", 350);
      m.put("10", 450);
      System.out.println("IdentityHashMap elements\n"+ m);
      System.out.println("\nSet of Values = " + m.values());
   }
}

The following is the output

IdentityHashMap elements
{2=200, 4=150, 9=350, 7=90, 10=450, 6=50, 5=110, 8=250, 1=100, 3=300}
Set of Values = [200, 150, 350, 90, 450, 50, 110, 250, 100, 300]
