Fetch the value for a specific key in Java IdentityHashMap

Java 8Object Oriented ProgrammingProgramming

To fetch the value for a specific key, use the get() method.

As a parameter, set the key you want to fetch and fetch the value.

Let’s say you need to fetch value of key 3

get("3")

The following is an example to fetch the value for a specific key in Java IdentityHashMap −

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);
      // Get the value of key 3
      System.out.println("\nThe Value of key 3 in IdentityHashMap = " + m.get("3"));
   }
}

Output

The output is as follows

IdentityHashMap elements
{2=200, 4=150, 9=350, 7=90, 10=450, 6=50, 5=110, 8=250, 1=100, 3=300}
The Value of key 3 in IdentityHashMap = 300
