Example

The following example shows the usage of java.util.WeakHashMap.values() method.

package com.tutorialspoint;

import java.util.Map;
import java.util.WeakHashMap;

public class WeakHashMapDemo {
   public static void main(String[] args) { 
      Map<String, String> weakHashMap = new WeakHashMap<String, String>();
            
      // put keys and values in the Map
      System.out.println("Putting values into the Map");
      weakHashMap.put("1", "first");
      weakHashMap.put("2", "two");
      weakHashMap.put("3", "three");
      
      // checking the size of the Map
      System.out.println("Map values: "+weakHashMap);  
      
      Collection col = weakHashMap.values();
      System.out.println("Collection values: "+col);  
   }      
}

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

Putting values into the Map
Map values: {1=first, 2=two, 3=three}
Collection values: [first, two, three]
