I'm having trouble accessing constants. I know it is always best to

The problem is on line 15 of the example you posted.
In other words, we don't know what you've tried, what error messages you
see, or what you are really attempting to do. Please provide an SSCCE
<http://sscce.org/> and then we'll be able to help without the use of
clairvoyance.
Well, I had a constant CLASSFILEPATH defined here...
__________________________________________________
package servlets;
import business.FileIO;
import business.Student;
import java.io.IOException;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class CalculateGradesServlet extends HttpServlet {
private String msg;
//private final String CLASSFILEPATH = "/WEB-INF/ClassList.txt";
[etc...]

And I thought it should be moved somewhere else so I put it here...
___________________________________________________
package business;
import java.util.Arrays;
public class Student {
private enum CALC {NONE, QUIZ, COURSE, LETTER};
public final String CLASSFILEPATH = "/WEB-INF/ClassList.txt";
[etc...]

Now note that the first file has an import for the second file. Still
the
constant cannot be seen inside the servlets package. The error is;
error: cannot find symbol
String path = sc.getRealPath(CLASSFILEPATH);
symbol: variable CLASSFILEPATH
location: class CalculateGradesServlet
1 error
You need to reference it as Student.CLASSFILEPATH. Or use import static.
