      Hashtable<Integer,String> htable1 = new Hashtable<Integer,String>();      
      // put values in table
      htable1.put(1, "A");
      htable1.put(2, "B");
      htable1.put(3, "C");
      htable1.put(4, "from");
      // get the hash code value
      System.out.println("Hash code value is :"+htable1.hashCode()); 

The code above generates the following result.
