Welcome to JavaRanch.

Do you know exactly what "immutable" means?

To make a class immutable, make sure that it does not have any non-private methods that change the internal state of instances of the clas (i.e. methods that change the values of member variables).

Also please use a meaningful subject line instead of "Java" when you ask a question.
