Homework #1. Chapter 7. PC# 2. Payroll Class (page 488-489)
Write a Payroll class that uses the following arrays as fields:
* employeeId. An array of seven integers to hold employee identification numbers. The array should be initialized with the following numbers: 5658845 4520125 7895122 8777541 8451277 1302850 7580489
* hours. An array of seven integers to hold the number of hours worked by each employee
* payRate. An array of seven doubles to hold each employee’s hourly pay rate
* wages. An array of seven doubles to hold each employee’s gross wages
The class should relate the data in each array through the subscripts. For example, the number in element 0 of the hours array should be the number of hours worked by the
employee whose identification number is stored in element 0 of the employeeId array. That same employee’s pay rate should be stored in element 0 of the payRate array.
The class should have a method that accepts an employee’s identification number as an argument and returns the
gross pay for that employee. Demonstrate the class in a complete program that displays each employee number and asks the user to enter that employee’s hours and pay rate. It should then display each employee’s identification number and gross wages.
Input Validation: Do not accept negative values for hours or numbers less than 6.00 for pay rate.

Expert Solution
Step 1: Algorithm :

Algorithm: Payroll Class

1. Create a class called Payroll.

2. Declare private fields in the Payroll class:
   - employeeId: an array of seven integers to hold employee identification numbers.
   - hours: an array of seven integers to hold the number of hours worked by each employee.
   - payRate: an array of seven doubles to hold each employee’s hourly pay rate.
   - wages: an array of seven doubles to hold each employee’s gross wages.

3. Create setter methods in the Payroll class:
   - setHours(index, hours):
     - If hours >= 0:
       - Set the hours at the specified index in the 'hours' array.
     - Else:
       - Print "Hours cannot be negative."

   - setPayRate(index, payRate):
     - If payRate >= 6.00:
       - Set the payRate at the specified index in the 'payRate' array.
     - Else:
       - Print "Employee pay rate cannot be less than $6.00/hour."

4. Create a method calculateWages(index) in the Payroll class:
   - Calculate gross wages as hours[index] * payRate[index].
   - Return the calculated gross wages.

5. In the main method:
   - Create an instance of the Payroll class (e.g., payroll).
   - Create a Scanner object (e.g., scanner) to read user input.

6. Use a for loop to iterate seven times (for each employee):
   - Prompt the user to enter hours for the employee with the current employeeId.
   - Read the entered hours and use payroll.setHours(index, hours) to set the hours for the current employee.
   - Prompt the user to enter the pay rate for the employee with the current employeeId.
   - Read the entered pay rate and use payroll.setPayRate(index, payRate) to set the pay rate for the current employee.

7. Print a header for the output:
   - Print "===========================\nEmployee ID\tGross Wages\n===========================".

8. Use a for loop to calculate and display the gross wages for each employee:
   - Calculate gross wages using payroll.calculateWages(index).
   - Print the employee ID and gross wages in a formatted manner.

9. End the program.
