Design by contract

Implement a use defined class called BankAccount whose objects represents real world
bank account entities. Each bankaccount object at a minimum should have a balance field.
Supply methods that allow deposit, withdraw and checking balance operations and other
necessary operations as you see fit. Also, implement a clone( ) method that creates a copy
of bankaccount object. Overwrite the equals( ) method of the Object class that helps to
check the contents of two bankaccount objects.
Ensure that you apply Design by Contract principles (preconditions/post conditions … )
and Defensive Programming techniques (assertions, exception handling …) while
implementing this user defined class. Make sure to include the preconditions and
postconditions, exceptions etc. as part of comments in the code.

Next create a test class that demonstrates the defensive mechanisms that you have put
in place in the use defined class.
