Educational Goals: Familiarity with the language and compiler.

Program Requirements

Write a Java program to compute your grade percentage for this class. The grade calculation is given on the syllabus. Your program should read in grades for each graded item (quizzes, homeworks, programs, and exams), and calculate the current percentage.

Your program should generate two outputs. First, the overall percentage should be calculated. For example, if the only graded item so far is the midterm, and the score was 100%, then the overall percentage should be 25. Second, the cumulative percentage should be calculated. The cumulative percentage is the percentage of points obtained for the items that have been graded. For example, if the only graded item so far is the midterm, and the score was 75%, then the cumulative percentage should be 75.

Assume there will be five programs worth 100 points apiece, three homeworks worth 10 points apiece, and three quizzes worth 10 points apiece. Both exams will be worth 100 points. You do not have to check whether the numbers are valid (that is, between -1 and 10 or -1 and 100).

Submission and Input Specifications

Your program will be compiled and run automatically. Therefore, it is very important that your program use the following naming convention, and that your programs accept inputs in the exact format that is specified here. Any program that does not adhere to these specifications will lose 10 points.

Submit your program as follows:

• Name your file "P1username.java" (note that this means your class name must be P1username.) To make sure we don't have duplicate names, please use your GMU osf1 email user name. For example, the TA would use the name "P1skime.java".
• Make sure your program will successfully compile and execute on OSF1.
• Send your Java source to skime@osf1.gmu.edu. Use the subject "590 P1 username" and only use an attachment if you are sure that her mail program can handle it. She uses pine on osf1 to read her email.

Your program must accept inputs from standard input (the keyboard) as follows:

• All inputs are integer.
• Use "-1" to represent an item that has not been graded yet.
• Read 13 inputs on separate lines in the order: 3 quizzes, 3 homeworks, 5 programs, 1 midterm, and 1 final.
• Example:

      10
      10
      -1
      0  
      8
      -1
      80
      79
      90
      -1
      -1
      95
      -1

When given the above inputs, your program should produce the outputs:

Overall Score: 45.84/100
Cumulative Score: 87.05/100

Grading Criteria

Your program will be graded on the following factors:

• 60% Correctness.
• 10% Adherence to input specification.
• 5% Use of modularity and procedural abstraction.
• 10% Variable names and type construction.
• 10% Comments and specification documentation.
• 5% Consistently readable formatting of the program source.
