求解，不知道自己哪里数组越界
【问题描述】P84 题目2
【输入形式】键盘输入学生人数，再依次输入这些学生的相关信息，包括姓名、年级、选课数，以及这几门所选课程的名称、学分信息。具体格式见样例。
【输出形式】依次输出所有学生的相关信息，包括学生姓名、年级，此学生所选选课的名称、学分，以及总学分数。具体格式见样例。
【样例输入】
input student count:2
input no 1 student name:Lucy
input no 1 student grade:2
input no 1 student course count:2
input no 1 course name:C
input no 1 course hour:2
input no 2 course name:DS
input no 2 course hour:3
input no 2 student name:Hellen
input no 2 student grade:3
input no 2 student course count:3
input no 1 course name:Java
input no 1 course hour:3
input no 2 course name:linux
input no 2 course hour:2
input no 3 course name:html
input no 3 course hour:2
【样例输出】
no 1 student information:
Lucy 2 grade
courses：
(1)C:2 hour
(2)DS:3 hour
hours:5
no 2 student information:
Hellen 3 grade
courses：
(1)Java:3 hour
(2)linux:2 hour
(3)html:2 hour
hours:7
【样例说明】
【评分标准】要求编写学生类Student、课程类Course和客户端类Client。学生类Student、课程类Course中应有合理的构造方法和数据成员的访问接口，编写学生类Student的getHours()方法，计算学生选课的总学分；编写学生类Student的ShowMessage()方法，打印输出学生信息（姓名、年龄、所有选课的名称、学分及总学分）；编写测试类，在控制台输入课程和学生信息，并打印出这些学生的选课信息。
代码如下：
import java.util.Arrays;
import java.util.Scanner;
public class Test {
public static class Student {
String name;
String grade;

}

this.name = name;
}
public String getGrade() {
return grade;
}
public void setGrade(String grade) {
this.grade = grade;
}
public Course[] getNum() {
return num;
}
public void setNum(Course[] num) {
this.num = num;
}
public Student(String name, String grade, Course[] num) {
super();
this.name = name;
this.grade = grade;
this.num = num;
}
@Override
public String toString() {
return name +grade+ " grade "+"\n"+"courses:"+"\n"+Arrays.toString(num);
}
public static class Course {

private int hour;

}

}

}
@Override
public String toString() {
return "Course [name=" + name + ", hour=" + hour + "]";
}
}
public static void main(String[] args) {
Scanner sc=new Scanner(System.in);
System.out.println("input student count:");
int a=sc.nextInt();

System.out.println("input no "+(j)+" course hour:");

System.out.println("no "+i+" student information:"+"/n"+name +grade+ " grade "+"\n"+"courses:"+"\n");
