Re: To Make class immutable which has ref to other mutable objects
a) Encapsulate the fields by marking as private and use 'getter' methods b) Mark them as final c) mark the class as final d) If you are worried any client might change a field when it is returned (for instance, change the value(s) of a MyTest member) you can return a deep copy of this object.
