     // returns the name and hashCode of this enum constant
     System.out.print("Programming in " + Language.C.toString());      
     System.out.println(", Hashcode = " + Language.C.hashCode()); 
     System.out.print("Programming in " + Language.Java.toString());  
     System.out.println(", Hashcode = " + Language.Java.hashCode());
