java 实现成绩排序

题目要求：
定义一个学生类；
包括学生学号 姓名 语数外成绩
要求输入5个学生信息
按语数外成绩总和排序输出学生信息

public class Student {

    String name;
        String sno;
        int Chinese;
        int Math;
        int English;

    public Student(String name, String sno, int chinese, int math, int english) {
        this.name = name;
        this.sno = sno;
        Chinese = chinese;
        Math = math;
        English = english;

    }

    public int total(){
        return this.Chinese+this.Math+this.English;
    }

    public void toPrint(){
        System.out.println(this.name+" "+this.sno+"  语文："+this.Chinese+"  数学："+this.Math+"  英语："+this.English);
    }


}
