How to Search Value in Hashtable Java

import java.util.Hashtable;

public class HashTableSearchValue {

public static void main(String[] args) {

Hashtable<Integer,String> ht = new Hashtable<Integer,String>();

/*
* Maps the specified key to the specified
* value in this hashtable
*/
ht.put(1, “java”);
ht.put(2, “jersey”);
ht.put(3, “spring”);
ht.put(4, “c”);
ht.put(5, “php”);

System.out.println(” value=java =”+ht.containsValue(“java”));
System.out.println(” value=ankush =”+ht.containsValue(“ankush”));
System.out.println(” value=java =”+ht.containsValue(“java”));

}
}

Output:

value=java =true

value=ankush =false

value=java =true
