Fetch the value for a specific key in Java IdentityHashMap

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
