When you create your own key object for use in a Hashtable, you must override the
Object.equals()
and
Object.hashCode()
methods since Hashtable uses a combination of the key's hashCode() and equals() methods to store and retrieve its entries quickly. It's also a general rule that when you override equals(), you always override hashCode().
