EnumMap Class containsValue() method

  • containsValue() method is available in java.util package.
  • containsValue() method is used to check whether the given value element (val_ele) maps one or more than one key associated or not of this enum map.
  • containsValue() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
  • containsValue() method does not throw an exception at the time of checking value mappings.


    public boolean containsValue(Object val_ele);


  • Object val_ele – represents the value element (val_ele) whose presence is to be checked.

Return value:

The return type of this method is boolean, it returns true when this enum map have one or more keys for the given value element (val_ele) otherwise it returns false.


// Java program to demonstrate the example 
// of boolean containsValue(Object val_ele) method 
// of EnumMap

import java.util.*;

public class ContainsValueOfEnumMap {
    public enum Colors {

    public static void main(String[] args) {
        // We are creating EnumMap object
        EnumMap < Colors, String > em =
            new EnumMap < Colors, String > (Colors.class);

        // By using put() method is to
        // add the linked values in an
        // EnumMap
        em.put(Colors.RED, "1");
        em.put(Colors.BLUE, "2");
        em.put(Colors.PINK, "3");
        em.put(Colors.YELLOW, "4");

        // Display EnumMap
        System.out.println("EnumMap :" + em);

        // By using containsValue() method isto
        // check whether this EnumMap contains
        // atleast one key element associated for the
        // given value element or not in an EnumMap
        boolean status = em.containsValue("3");

        // Display status of EnumMap
        System.out.println("em.containsValue(3): " + status);


EnumMap :{RED=1, BLUE=2, PINK=3, YELLOW=4}
em.containsValue(3): true
