I need it today in parts.
Payroll Program Part 1
Create a non-GUI based Java application that calculates weekly pay for an
employee. The application should display text that requests the user input the name of the employee, the hourly rate, and the number of hours worked for that week. The application should then print out the name of the employee and the weekly pay amount. In the printout, display the dollar symbol ($) to the left of the weekly pay amount and format the weekly pay amount to display currency.
Payroll Program Part 2
Modify the Payroll Program application so it continues to request employee information until the user enters stop as the employee name. In addition, program the application to check that the hourly rate and number of hours worked are positive numbers. If either the hourly rate or the number of hours worked is not a positive value, the application should prompt the user to enter a positive amount.
Payroll Program Part 3
Modify the Payroll Program so that it uses a class to store and retrieve the employee's name, the hourly rate, and the number of hours worked. Use a constructor to initialize the employee information, and a method within that class to calculate the weekly pay. Once stop is entered as the employee name, the application should terminate. Make sure the program maintains all the functionality required in previous assignments and your source code is readable and well documented. Use feedback you have received from the instructor to make any needed modifications.
