一个有趣的问题 :对象数组?

//一个学校有gradeCount个班级,每个班级又有classCount个学生,那么Class,Grade,School的构造函数怎么写?



//班级类
public class Class
{
Student[] student;

public Class(int studentCount) //怎么写
{

}
}

//年级类
public class Grade
{
Class[] classs;
public Grade() //怎么写
{
}

}

//学校类
public class School
{
Grade[] grade;
public School() //怎么写
{
}

}

//班级类
public class Class
{
Student[] student;

public Class(int studentCount) //怎么写
{
if(strudentCount <= 0)
throw new ArgumentException();
student = new Student[studentCount];

}
}

//年级类
public class Grade
{
Class[] classes;
public Grade(int classCount) //怎么写
{
if(classCount <= 0)
throw new ArgumentException();
classes = new Class[classCount];
}

}

//学校类
public class School
{
Grade[] grade;
public School(int gradeCount) //怎么写
{
if(gradeCount <=0 )
throw new ArgumentException();
grade = new Grade[gradeCount];
}

}

public class Class
{
Student[] student;

public Class(Student[] student)
{
this.student = student;
}
}

public class Grade
{
Class[] classs;
public Grade(Class[] classes)
{
this.classes = classes
}

}

public class School
{
Grade[] grade;
public School(Grade[] grade)
{
this.grade = grade;
}
}

要通过构造函数将gradeCount,classCount传递进去.
