Chapter 9, Problem 8E
Create a class Rational that represents a rational number. It should have private attributes for
- The numerator (an integer)
- The denominator (an integer)
and the following methods:
- Rational (numerator, denominator) — a constructor for a rational number.
- Accessor methods getNumerator and getDenominator and mutator methods setNumerator and setDenominator for the numerator and the denominator.
You should use an exception to guarantee that the denominator is never zero.

Define the class InvalidSideException, which inherits from the Exception class. Also define a Square class, which has one method variable -- an int describing the side length. The constructor of the Square class should take one argument, an int meant to initialize the side length; however, if the argument is not greater than 0, the constructor should throw an InvalidSideError. The Square class should also have a method getArea(), which returns the area of the square.Create a Driver class with a main method to test your classes. Your program should prompt the user to enter a value for the side length, and then create a Square object with that side length. If the side length is valid, the program should print the area of the square. Otherwise, it should catch the InvalidExceptionError, print "Side length must be greater than 0.", and terminate the program.

In this java assignment, we will be creating a paystub for an employee using classes, files, getters, and setters. Each file should only have one class and the class should share the same name as the file. We are going to implement the following classes:
Employee - This class represent the employee. It needs the following fields exposed via getters and setters:
Employee ID (hard code it to 1)
First name, last name, middle initial
Address, city, zip
Phone, email
Hourly rate
PayPeriod - This class represents an employee's payment information. An employee will eventually have more than one pay period. It needs the following fields exposed via getters and setters:
Pay period Id (hard code to 123456)
Employee Id
Start date, end date
Number of hours
PayrollManager - This class provides the functionality we need to compute and display the payroll. It should implement the following methods:
double CalculateGrossPay (Employee, PayPeriod) - this should return the total gross for the…
