java程序设计，求代码 1.定义学生类，学生类有学号，姓名，语文成绩，数学成绩的属性和有参的构造
import java.util.Comparator;
public class Student implements ComparableStudent {
private int no;
private String name;
private String sex;
private int roomNo;
private double score;
public Student(int no, String name, String sex, int roomNo, double score) {
this.no = no;
this.name = name;
this.sex = sex;
this.roomNo = roomNo;
this.score = score;
}
public Student(int no, String name, String sex, double score) {
this.no = no;
this.name = name;
this.sex = sex;
this.score = score;
}
public int getNo() {
return no;
}
public void setNo(int no) {
this.no = no;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public int getRoomNo() {
return roomNo;
}
public void setRoomNo(int roomNo) {
this.roomNo = roomNo;
}
public double getScore() {
return score;
}
public void setScore(double score) {
this.score = score;
}
@Override
public int compareTo(Student o) {
if (this.no o.no) return 1;
else if (this.no o.no) return -1;
else return 0;
}
@Override
public String toString() {
return "Student{" +
"no=" + no +

'}';
}
}
//性别比较器类
class SexComparator implements ComparatorStudent {
@Override
public int compare(Student o1, Student o2) {
if (o1.getSex().compareTo(o2.getSex()) 0) return 1;
else if (o1.getSex().compareTo(o2.getSex()) 0) return -1;
else return 0;
}
}
//寝室号比较器类
class RoomNoComparator implements ComparatorStudent {
@Override
public int compare(Student o1, Student o2) {
if (o1.getRoomNo() o2.getRoomNo()) return 1;
else if (o1.getRoomNo() o2.getRoomNo()) return -1;

}
}
//入学成绩比较器类

}
}
import java.util.ArrayList;
import java.util.Arrays;
import java.util.Collections;
import java.util.List;
public class TestStudent {

ListStudent studentList=new ArrayList();
studentList.add(s1);

studentList.add(s3);
studentList.add(s4);
Collections.sort(studentList);
System.out.println(Arrays.toString(studentList.toArray()));
}
}
求大神补全java代码：java创建一个student类
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);
