java解释正确

Question

我有以下问题，想知道我是否正确解释了这个问题。我是Java和编程的新手，所以技术术语甚至认为我读了我的教科书并理解它们我不确定如果我已经正确编程了它们。请看问题，让我知道我在做什么是正确的方向。

问题本身：

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.

那么这是我到目前为止的代码是正确的吗？我的意思是我宣布构造函数的方式和... tks

   {
       mark_assig = assigmarks;
   }

   public int getassigMark()
   {
       return mark_assig;
   }


   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

一般来说，如果您接受其他答案中的评论。

但是，您的命名约定有点古怪。标准的java bean约定是使用camelCase命名你的属性（你的整数等）（所以是markQuiz而不是mark_quiz），你的getter和setter命名为getMarkQuiz和setMarkQuiz（get / set之后的第一个字母现在是大写的）对于布尔属性，使用isXxx（）而不是getXxx（）。

这些约定被广泛使用，将使您的代码更加工具友好（使用ecliipse / netbeans等ide）

关于你的问题之后的评论，家庭作业问题通常是不受欢迎的，这就是你投票的原因。通过玩耍和试验，弄错并修复它，你会学到更多东西，而不是来这里寻求答案。至少你确实提供了一个骷髅答案，所以你正在思考它，为此做得很好。保持它！！/ / p>
