OOP1 Lab - 07 - Fall

1. The document provides instructions for a lab assignment on object oriented programming. Students are asked to continue developing classes from the previous lab and create new classes. 2. Students should create a Calculator class with methods for basic arithmetic operations and check for exceptions. They should also create an Account class to represent bank accounts with methods like deposit, withdraw, and transfer between accounts. 3. Two custom exception classes are to be created - ZeroAsParameterException to handle zero parameters and NegativeResultException to handle negative results from certain operations. Students must follow naming conventions and declare members and methods properly.

2. Develop Java Classes:

Calculator double x Member variables


Class double y Declare Private
2 Constructor (Empty, valued) Declare public

double add(double x, double y) Declare public


double sub(double x, double y)
double mul(double x, double y)
double div(double x, double y)
ArithmeticException Check arithmetic dependency

IOException Check Input Output Exceptions

Use java.utill.Scanner class to take input from the console.

The program will ask for the choice of operation from the user first. User will input the choice then the
value of the operations will be given.

Account Class String accName Member variables

deposit(int amount)
Withdraw(int amount)

transfer(int amount, Account Transfer amount from one


receiver) account to another account

Exception Class ZeroAsParameterException if any of the parameter is 0 (zero)
