Answer / kanchan
1. Don't provide any methods that modify the object
2. Ensure that no methods may be overridden. This prevents
careless or malicious subclasses from compromising the
immutable behavior of the class. Preventing
method overrides is generally done by making the class final
3. Make all fields final.
4. Make all fields private. This prevents clients from
modifying fields directly.

Answer / al rahid
1. Declare the Class as final (this inherently makes all
member function final)
2. Declare member variables private (not necessarily final,
because private instance variable are accessed via public
member functions only, e.g. in java.lang.String class,
variable "hash" is declared as "private int hash;" with no
final keyword).
