      System.out.println("Putting values into the Map");
      weakHashMap.put("1", "first");
      weakHashMap.put("2", "two");
      weakHashMap.put("3", "from java2s.com");
      
      // checking the size of the Map
      System.out.println("Map values: "+weakHashMap);  
      
      Collection col = weakHashMap.values();
