Question

所以这就是我的困境：我有一个文本文件，其中包括学生名单和归因于他们的详细信息，例如他们的学生证，他们的姓名，学期完成了几个小时，他们的专业......等等。以下是文件的外观：

222545767
name
Computer Science
15
60
222123767
name name
Computer Science
12
45
222334111
first last

54
622909311

222766721

222123456

现在，当我读入文本文件时，我希望将每个学生分配到一个数组对象。我对如何做到这一点非常模糊，但到目前为止这是我的代码：

public class Student
{

private int id;
private String firstName;
private String lastName;
private String major;
private int hoursCompleted;
private int gradePoints;
Student[] studentsArray = new Student[30];  

public Student()
{

}

public Student(int id, String firstName, String lastName,
        String major, int hoursCompleted, int gradePoints)
{

}





public void readStudentsfile(){
    String fileName = "Students.txt";
    Scanner inputStream = null;

    try
    {
        inputStream = new Scanner(new File(fileName));
    }
    catch (FileNotFoundException e)
    {
        System.out.println("error");
        System.exit(0);
    }

    while(inputStream.hasNextLine()){
        int id = inputStream.nextInt();
        String firstName= inputStream.next();
        String lastName= inputStream.next();
        String major= inputStream.nextLine();
        int hoursCompleted= inputStream.nextInt();
        int gradePoints= inputStream.nextInt();

        studentsArray[1] = new Student(id, firstName, lastName, major, hoursCompleted, gradePoints);
         // this part is not correct but is where I need to assign
         // all of the variables read from the file into array objects
    }
    inputStream.close();
}

从文本文件JAVA中分配每个数组对象
