Help with Payroll class

[mags11]

I have a program that uses 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
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.

I've had a number of errors when I compile it:

Payroll1.java:34: cannot find symbol

EmployeeID = ID;

Payroll1.java:35: cannot find symbol

^
Payroll1.java:71: incomparable types: int[] and int

^

return GrossPay;

The code is as follows:

     public class Payroll1
     {
      public final int NUM_EMPLOYEES = 7;   // constants of employees
      private int[] EmployeeID = {5658845, 4520125, 7895122, 8777541, 8451277, 
      1302850, 7580489};

      private double[] hours = new double[NUM_EMPLOYEES];
      private double[] payRate = new double[NUM_EMPLOYEES];
      private double[] GrossPay = new double[NUM_EMPLOYEES];

      public double getGrossPay(int i)
      {
     return payRate[i] * hours[i];
      }

   /** Constructor
   @param employeeID.
   @param hours.
   @param payRate.
   */

      public Payroll1(int[] EmployeeID, double[] hours, double[] payRate)
      { 
     EmployeeID = ID;
     payRate = pr;
     hours = hr;
      }
      public int getEmployeeID(int i)
      {
       return EmployeeID[i]=ID;
      }
      public void setEmployeeID(int i, int ID)
      {
      EmployeeID[i]=ID;
      }

      public void setPayRate(int i, double pr)
      {
      if(pr>=6.00)
        payRate[i]= pr;
      }
      public double getPayRate(int i)
      {
     return payRate[i]= pr;
      }

      public void setHours(int i, int hr)
      {
      if(hours>=0)
        hours[i]= hr;
      }
      public int getHours(int i, int hr)
      {
      return hours[i]= hr;
      }

      public double getGrossPay(int ID, int i) 
      {
     for( int i=0; i<NUM_EMPLOYEES; i++)
     {
        if(EmployeeID == i)
        {
           GrossPay[i] = hours[i]* payRate[i];
           return GrossPay;
        }
     }  
     return 0.0;
  } 
 }

Where are the definitions for the variables refered to by the error message: cannot not find symbol
The compiler can not find definitions for them that are in scope where they are used.

Line 25:

EmployeeID = ID;

Assigning a vlalue to an argument passed to a method is a waste of time, When the method exits, the variable's value is lost

those errors are quite self-explaining.
for some of them, you are using a variable you haven't declared yet.

for others, your application expects a single double, while you pass an array of doubles. considering the first is a primitive, and the second is an object, this should be clear why that's a huge mistake.
