类java解释正确吗

Question

我有下面的问题，想知道我对这个问题的解释是否正确。我对Java和编程还不熟悉，所以技术术语甚至认为我读过我的教科书并理解了它们，我不确定我是否正确编程了它们。请看问题并让我知道我所做的是否正确

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.

这就是我目前掌握的代码，对吗？我的意思是我声明构造函数的方式等等。。。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

一般来说，如果你接受另一个答案中的评论，就可以了

然而，您的命名约定有点古怪。标准的JavaBean约定是用camelCase（所以是markquick而不是mark_quick）来命名你的属性（你的int等等），把你的getter和setter命名为getmarkquick和setmarkquick（get/set后面的第一个字母现在大写），对于布尔属性，使用isXxx（）而不是getXxx（）

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

关于你在提问后的评论，家庭作业问题通常是不受欢迎的，这就是你被否决的原因。你将通过游戏和实验，犯错，然后纠正错误，而不是来到这里寻求答案，学到更多的东西。至少你提供了一个基本答案，所以你正在考虑，做得很好。继续
