JAVA

2. Payroll Class 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 employees hourly pay rate wages. An array of seven doubles to hold each employees 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 employees pay rate should be stored in element 0 of the payRate array. In addition to the appropriate accessor and mutator methods, the class should have a method that accepts an employees 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 employees hours and pay rate. It should then display each employees identification number and gross wages. Input Validation: Do not accept negative values for hours or numbers less than 6.00 for pay rate.

Need help!! So far, I have done the code but getting error

public class Payroll { private int [] employeeID = { 5658845, 4520125, 7895122, 8777541, 8451277, 1302850, 7580489 }; private final int NUM_OF_EMPLOYEES = 7; private int [] hours = new int [7]; private double [] payRate = new double [7]; private double [] wages = new double [7]; private double []grossPay = new double[7]; public Payroll() { // initialize all other arrays with 0 values
