Answer to Question #231869 in Java | JSP | JSF for jerry

Question

Develop a java application using Inheritance as per the following. Create a super class called

CashTree which demonstrate any ATM Machine. Have attributes like name, codeno, location,

etc. Add functionalities like ViewBalance, WithDraw and Deposit in super class. Derive two

sub classes SBI_Bank, and HDFC_Bank with additional properties such as customer_name,

balance and redefine those super class functionalities according to the nature of specified

bank (differenciate via service_charges, interest rate, and maximum withdraw limit etc).

Complete the above scenario using Inheritance, Run Time Polymorphism with Menu driven

options.
