Hi, I've got a homework assignment that requires us to make multiple classes in multiple files (1 class per file) and then have a main file that utilizes the classes within the other files. Here's how my classes and sub classes are setup:
employee -> paid & volunteer
paid -> hourly & monthly & executive

My files are employee.java, paid.java, volunteer.java, hourly.java, monthly.java, and executive.java; all of these are in the same package called employees. I also have a mainApp.java that utilizes the other files.

The problem I'm having is with the volunteer.java, when I compile it it gives these errors:
Error 1)
volunteer.java:13: cannot find symbol
symbol: class employee
class volunteer extends employee{

Error 2)
volunteer.java:42: cannot find symbol
symbol : variable super
location: class employees.volunteer
String top = super.toString();

And heres the code for volunteer.java:

Code:

package employees;

import java.util.*;
import java.io.*;
import java.text.*;

class volunteer extends employee{

	private String type;
	private double earn;
	/*private String fname = super(fname);
	private String lname = super(lname);
	private String address = super(address);*/

	public volunteer()
	{
		super();
		type = "Volunteer";
		earn = 0.0;
	}

	public volunteer(String first, String last, String addrs)
	{
		super(first, last, addrs);
		type = "Volunteer";
		earn = 0.0;
	}

	public double earnings()
	{
		return this.earn;
	}

	public String toString()
	{
		String top = super.toString();
		return this.type + "\n" + top;
	}
}

Anyone see what's wrong?
