Example

The following example shows the usage of java.util.LinkedHashMap.containsValue() method.

package com.tutorialspoint;

import java.util.*;

public class BitSetDemo {

   public static void main(String[] args) {

      // create a new linked hash map
      LinkedHashMap map = new LinkedHashMap(5);

      // add some values in the map
      map.put("One", 1);
      map.put("Two", 2);
      map.put("Three", 3);

      // print the map
      System.out.println("Map:" + map);

      // check if map contains 3
      System.out.println("" + map.containsValue(3));

      // check if map contains 5
      System.out.println("" + map.containsValue(5));
   }
}

Let us compile and run the above program, this will produce the following result:

Map:{One=1, Two=2, Three=3}
true
false
