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
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
"+ m);
// Get the value of key 3
System.out.println("
The 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
