java - 如何根据用户的需要创建尽可能多的对象？

Question

我即将完成一项作业，我将引用该作业(我不是要求您为我做，我只是不知道如何开始)

Your task is to write a (very simple:-) student record system. You should be able to store details about students - their name, subject and a student number; as well as the level they have most recently completed ranging from 0 (meaning they are still in the first year) through to 3 (meaning they have graduated). It should also store their result for each level they have completed as a number 0-100. Your program should allow the user to enter student data for as many students as they want.

这是否可以通过对象来完成，因为我对此部分感到非常困惑..

任何建议都会有帮助，我可以做除这部分之外的所有事情。

Answer 1

Student应该是一个类并包含提到的所有属性。一旦您拥有Student你可以上的课Student允许您拥有 ArrayList<Student> 的对象因此，您可以存储任意数量的学生。例如:

ArrayList<Student> students = new ArrayList<Student>();

while(youWantToReadStudents){
   Student student = new Student();
   // read and add student details
   students.add(student); // add student to ArrayList
}

请注意循环如何允许您将学生添加到 ArrayList只要youWantToReadStudents == true 。
