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
