11.18 Composition Assignment

Write a Java program that prompts user for a file name, opens and reads the data, process, and store them in an array or ArrayList of students. A Student (you need to declare it) is a class defining a Student with information (such as name, id and a list of courses) and associated operations; Course is a class containing information (such as name, grade and number of units) and associated operations. The program calculates the total completed units and GPA for a student. The program then prints a table to the monitor and stops execution. (Refer to the sample below.)

Use the following table to assign points for a course:

Grade	Points
A	4.0
B	3.0
C	2.0
D	1.0
F	0.0

To calculate the GPA multiply units by points for each course, and then add then together and divide the sum by total units. For example if course 1 has 5 units and the grade is A (4 points) and course 2 has 4 units and the grade is B (3 points), and course 3 has 4 units and the grade is F then (4 * 3 + 5 * 4 + 4 * 0)/13 = 2.462. Completed course are all the courses that have a passing grade (a, b, c, and d), Units taken is sum of all units registered for.

Completed courses are considered the ones with passing grade (A,B,C,D).

Requirements:

• Develop a class to represent a Student (the following data members must be included, more is OK) :
  • Name (First, Last)
  • Id number
  • list of courses
  • number of units taken
  • units completed
  • units taken
  • average.
• Develop a class to represent a Course(the following data members must be included, more is OK):
  • Course Name
  • Course Units
  • Course Grade
• Program must be modular (all tasks must be done in methods)
• Must include methods to process array of students
• UML representation of classes
• Prompt user for all input and output file names
• Use attached data file to test your program.
• Error check files
• If you use an array, set array size to 20 for students and courses, but when adding elements check the size to make sure not to overflow the array.

Final report to the monitor and output file
