This is the Error I get when I compile and Run:

Error: Could not find or load main class Employee.EmployeeTest

main is static. It has to be static so that when a program starts it can find main() without needing to create the instance of an object.

public static void main(String[] args) {
  ...
}

Being that you don't have static it is being seen as an instance method. There it isn't seen by the class loader and returns that error.

P.S. Your main function is not doing anything, so don't expect it to create objects or run functions. You have to do something in your main function.

Thank you for helping me,

So should I move the objects i created inside the main function because I have tried that as well and i get errors inside the class. I am really confused on this test class method been working on it all day. Do you have any more suggestions that may be of some help?

[GregBrannon]

I assume you mean that you've tried a main() method that looks like:

public static void main(String[] args)
{
    UnionEmployee emp1 = new UnionEmployee("John Henry", "Maintenance", 15.00, 0.08);
    CommissionEmployee emp2 = new CommissionEmployee("Elizabeth Thompson", "Human Resources", 17.00);
    Employee emp3 = new Employee("Jordan Bullock", "Operations", 13.50);
}

And I can see how that will cause errors, because the variable emp1 is used in the two other methods in that class, but those methods don't know what emp1 is. emp1 was declared and initialized in the main() method, so the variable emp1 is a "local variable" to the main() method, unknown outside main().

The fix that occurs first to me is: change emp1 from a main() local variable to a class variable, but then I wonder if the display() methods require emp1. Each of those methods has their own local Employee variables, emp and uEmp, so I'm thinking it's the methods that need modifying: remove emp1 entirely.

Since the main() method I suggested above doesn't call either of those methods, we'll need to add those calls to main():

public static void main(String[] args)
{
    UnionEmployee emp1 = new UnionEmployee("John Henry", "Maintenance", 15.00, 0.08);
    CommissionEmployee emp2 = new CommissionEmployee("Elizabeth Thompson", "Human Resources", 17.00);
    Employee emp3 = new Employee("Jordan Bullock", "Operations", 13.50);
    
    display( emp3, 40 );
    display( emp1, emp2, 35 );
}

Then, since a static method main() is calling those methods, they will also have to be static:

static void display(Employee emp, int numOfHourWorked) 
{
    System.out.println( "Name and department :" + emp.getNameAndDepartment() );
    System.out.println( "Weekly pay of employee :"
            + emp.weeklyPay(numOfHourWorked));
}

static void display(UnionEmployee uEmp, CommissionEmployee cEmp,
        int numOfHourWorked)
{
    System.out.println("Weekly Pay for UnionEmployee"
            +  uEmp.weeklyPay(numOfHourWorked));
    System.out.println("Weekly Pay for UnionEmployee"
            + cEmp.weeklyPay(numOfHourWorked));
}

There are other logic errors to correct, but hopefully you can see how to do those now that it's running.

Keep coding!
