求大神補全java代碼：java創(chuàng)建一個student類

class Student{

private String name;

private int num;

private String course1;

private String course2;

private String course3;

private String course4;

private String course5;

private String course6;

private String course7;

private String course8;

private String course9;

private String course10;

public String toString() {

return "OrderStatus [name=" + name + ", num=" + num + ", course1="

+ course1 + ", course2=" + course2 + ", course3=" + course3

+ ", course4=" + course4 + ", course5=" + course5

+ ", course6=" + course6 + ", course7=" + course7

+ ", course8=" + course8 + ", course9=" + course9

+ ", course10=" + course10 + "]";

}

}

public class Main{

public static void main(String[] args){}

Student student = new Student();

system.out.println(student.toString);
