Question

I have the below question, and would like to know if I have interpreted the question right or not. I am new to the Java and programming so the technical terms even thought I read my textbook and understood them I am not sure that if I have programmed them correctly. Please see the question and let me know if what I am doing is in the right direction.

The question itself:

You are asked to implement a class to keep track of the students' academic result for a module. The system requires the following information about a student:
 Student identification - a unique 7-digit identification that begins with 'S' for local students and 'F' for foreign student. E.g. S1234567.
 Student name
 Quiz mark - an integer number in the range of 0 to 100
 Assignment mark - an integer number in the range of 0 to 100
 Exam mark - a floating point number in the range of 0 to 100
 Resit student - true if the student is retaking the paper, false otherwise. Resit student does not have quiz and assignment marks.
Write a Java class called Student and provide the following:
 suitable instance variables for the information described above
 constructor(s) with the appropriate actions on the instance variables
 the accessor methods for the instance variables
 the computeScore() method to compute the score as follows:
for resit students, take only the exam mark as the score
for other students, score is calculated by using the formula
9% * quiz + 21% * assignment + 70% * exam
The score calculated is to be rounded up to the nearest integer and returned.
 the findGrade() method that returns the grade based on the score:

Score range
Grade
80 to 100
A
70 to 79
B
60 to 69
C
50 to 59
D
0 to 49
F
 the toString() method that returns the attribute values as a string with description.

then this is the code i have so far is that correct? i mean the way i declared the constructors and such…tks

   public int computerScore()
   {
       /*do as the program asks then return the computer score */



   }



   public String findGrade()
   {
       // Based on the computeScore() I have to access what is the grade and return that
   }

   public String toString()
   {
       // What is this method supposed to do?
   }

}

Answer 1

generally ok, if you take on board the comments made in the other answer.

However, your naming conventions are a bit wacky. Standard java bean convention is to name your properties (your ints and so on) with camelCase (so markQuiz rather than mark_quiz) and your getters and setters as getMarkQuiz and setMarkQuiz (the 1st letter after get/set is now capitalized) For boolean properties, use isXxx() rather than getXxx().

These conventions are widely used and will make your code more tool friendly (with ides such as ecliipse/netbeans)

Regards to your comment after your question, homework questions are generally frowned upon, which is why you got down voted. You will learn far more by playing and experimenting, getting it wrong and then fixing it, than by coming here asking for an answer. At least you did provide a skeleton answer, so you are thinking about it, so well done for that.Keep at it!
