Immutable class Immutable class can be made by following these rules: 1) Providing of "setter" methods is not recommended. Setter methods are the methods that modify fields or objects referred to by fields. 2) Making all fields final and private and it doesn't allow subclasses to override the methods. 3) Instance fields that includes references should not be allowed to have mutable objects. 4) Create copies of your internal mutable objects when necessary to avoid returning the originals in your methods.
