The following is the error I am getting:....java:21: error: method printGrade in class HwScore cannot be applied to given types;
homework.printGrade();
^
required: int
found: no arguments
reason: actual and formal argument lists differ in length
1 error
Tool completed with exit code 1

On this snippet of code:
//*******************************
//From the class file:
//*******************************
// this method enables the printing of individual assignments points, max points, and grade public void printGrade(int hwNumber) { double grade; // grade percentage for individual assignment double earned = 0; // how many points earned on current assignment double possible = 0; // how many points possible on current assignment earned = earnedPoints[hwNumber]; //earned is element of earnedPoints[] specified in printGrade call possible = possiblePoints[hwNumber]; //possible is element of possiblePoints[] specified in printGrade call grade = (earned / possible); if (grade >= letterGrade[0]) { System.out.println("On this homework, you earned " + earned + " out of " + possible + " possible points: A"); } else if (grade >= letterGrade[1]) { System.out.println("On this homework, you earned " + earned + " out of " + possible + " possible points: B"); } else if (grade >= letterGrade[2]) { System.out.println("On this homework, you earned " + earned + " out of " + possible + " possible points: C"); } else if (grade >= letterGrade[3]) { System.out.println("On this homework, you earned " + earned + " out of " + possible + " possible points: D"); } else { System.out.println("On this homework, you earned " + earned + " out of " + possible + " possible points: F"); } // end if else statement }// end printGrade

//**********************************************
I think the problem is that printGrade() needs to take a parameter but I thought that is what I was doing by declaring (int hwNumber). Do I create another method with that information or is there something wrong with my printGrade method.

That's making it need a parameter. Since you've done that you need to give it a parameter (which you're not doing)
