JAVA类与对象 定义一个student类

定义一个student类，其中有成员变量，学号，姓名，性别，是否为班干部，以及语文数学英语的分数，求成绩的方法。
定义一个主类，主方法中通过学生类创造对象，通过键盘输入学生的属性值，然后输出学生的属性值，调用方法输出该学生的总成绩和平均成绩。

import java.util.Scanner;

public class HelpOther {
    public static void main(String[] args) {
        Scanner scanner=new Scanner(System.in);
        System.out.println("请输入学生学号:");
        String id=scanner.nextLine();
        System.out.println("请输入学生姓名:");
        String name=scanner.nextLine();
        System.out.println("请输入学生性别(1:男生 0：女生):");
        String isMan=scanner.nextLine();
        boolean man=false;
        if(isMan.equals("1")){
            man=true;
        }
        System.out.println("请输入学生是否领导(1:是 0：不是)");
        String isLeader=scanner.nextLine();
        boolean leader=false;
        if(isLeader.equals("1")){
            leader=true;
        }
        System.out.println("请输入学生数学分数");
        float mathScore=scanner.nextFloat();
        System.out.println("请输入学生语文分数");
        float chineseScore=scanner.nextFloat();

        Student student=new Student(id,name,man,leader,mathScore,chineseScore);
        System.out.println(student.avScore);

    }

}

class Student {
    String id; //学号
    String name;//姓名
    boolean isMan;//是否男生
    boolean isLeader;//是否领导
    float mathScore;//数学分数
    float chineseScore;//语文分数
    float avScore;//平均成绩

    public Student(String id ,String name,boolean isMan,
                   boolean isLeader,float mathScore,float chineseScore){
        this.id=id;
        this.name=name;
        this.isMan=isMan;
        this.isLeader=isLeader;
        this.mathScore=mathScore;
        this.chineseScore=chineseScore;
        //计算平均分数
        this.avScore=(mathScore+chineseScore)/2;
    }

}

如有帮助望采纳哈哈。

怎么这么多student类的问题，我看我是要博客上写个student类的总结报告了。。。

运行结果：

//学生类
public class Student {
    //成员变量
    private int studentNumber;
    private String StudentName;
    private String StudentGender;
    private boolean classCadre;
    private double chineseScore;
    private double mathScore;
    private double englishScore;

    //构造方法
    public Student(){
    }
