We can use containsValue() method to search a value in hashmap in java.
containsValue(Object v): Returns true if this map contains specified value otherwise returns false.
Syntax:
public boolean containsValue(Object v)
Example
package com.w3schools; import java.util.HashMap; public class Test { public static void main(String args[]){ //Create HashMap object. HashMap<Integer, String> hashMap = new HashMap<Integer, String>(); //Add objects to the HashSet. hashMap.put(4, "Roxy"); hashMap.put(2, "Sunil"); hashMap.put(5, "Sandy"); hashMap.put(1, "Munish"); hashMap.put(3, "Pardeep"); //Print the HashMap object. System.out.println("HashMap elements:"); System.out.println(hashMap); if(hashMap.containsValue("Sandy")){ System.out.println("Hashmap contains value Sandy"); } else { System.out.println("Hashmap does not contains value Sandy"); } } } |
Output
HashMap elements: {1=Munish, 2=Sunil, 3=Pardeep, 4=Roxy, 5=Sandy} Hashmap contains value Sandy |
