帮我写一个java学生成绩管理面板 ，要求有学生类（ZSStudent），成绩类（ZSGrade），管理类（ZSSrudentManagerSystem），程序运行入口：ZSStudentManagerSystem.run（）；

好的，我可以帮您编写一个Java学生成绩管理面板。以下是代码示例：

ZSStudent.java：

public class ZSStudent {
    private String name;
    private int age;
    private String id;

    public ZSStudent(String name, int age, String id) {
        this.name = name;
        this.age = age;
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }
}

ZSGrade.java：

import java.util.HashMap;

public class ZSGrade {
    private HashMap<String, Double> grades;

    public ZSGrade(HashMap<String, Double> grades) {
        this.grades = grades;
    }

    public Double getGrade(String courseId) {
        if (grades.containsKey(courseId)) {
            return grades.get(courseId);
        } else {
            return 0.0;
        }
    }

    public void setGrade(String courseId, Double score) {
        grades.put(courseId, score);
    }

    public double getAverage() {
        double sum = 0.0;
        for (Double score : grades.values()) {
            sum += score;
        }
        return sum / grades.size();
    }
}

ZSStudentManagerSystem.java:

import java.util.HashMap;
import java.util.Scanner;

public class ZSStudentManagerSystem {
    private static HashMap<String, ZSGrade> gradeMap = new HashMap<>();
    private static Scanner scanner = new Scanner(System.in);

    public static void run() {
        while (true) {
            printMenu();  // 打印菜单

            int option = scanner.nextInt();

            switch (option) {
                case 1:
                    addNewStudent();  // 添加学生
                    break;
                case 2:
                    addNewGrade();  // 添加成绩
                    break;
                case 3:
                    printGrade();  // 显示成绩
                    break;
                case 4:
                    System.out.println("谢谢使用，再见！");
                    return;
                default:
                    System.out.println("输入错误，请重新选择！");
            }
        }
    }

    private static void printMenu() {
        System.out.println("学生成绩管理系统");
        System.out.println("-----------------------");
        System.out.println("1. 添加学生");
        System.out.println("2. 添加成绩");
        System.out.println("3. 显示成绩");
        System.out.println("4. 退出");
        System.out.println("-----------------------");
        System.out.println("请选择功能：");
    }

    private static void addNewStudent() {
        System.out.println("请输入新学生的姓名：");
        String name = scanner.next();

        System.out.println("请输入新学生的年龄：");
        int age = scanner.nextInt();

        System.out.println("请输入新学生的学号：");
        String id = scanner.next();

        ZSStudent student = new ZSStudent(name, age, id);
        gradeMap.put(id, new ZSGrade(new HashMap<String, Double>()));
        System.out.println("添加学生成功！");
    }

    private static void addNewGrade() {
        System.out.println("请输入成绩所属学生的学号：");
        String studentId = scanner.next();

        if (!gradeMap.containsKey(studentId)) {
            System.out.println("该学生不存在！");
            return;
        }

        System.out.println("请输入课程名称：");
        String courseId = scanner.next();

        System.out.println("请输入成绩：");
        double score = scanner.nextDouble();

        ZSGrade grade = gradeMap.get(studentId);
        grade.setGrade(courseId, score);
        System.out.println("添加成绩成功！");
    }

    private static void printGrade() {
        System.out.println("请输入要查询的学生学号：");
        String studentId = scanner.next();

        if (!gradeMap.containsKey(studentId)) {
            System.out.println("该学生不存在！");
            return;
        }

        ZSGrade grade = gradeMap.get(studentId);
        System.out.println("学生姓名：" + grade.getName());
        System.out.println("学生年龄：" + grade.getAge());
        System.out.println("学生学号：" + grade.getId());
        System.out.println("-----------------------");
        System.out.println("| 课程名称\t| 成绩\t|");
        System.out.println("-----------------------");

        for (String courseId : grade.getCourseIds()) {
            System.out.println("| " + courseId + "\t\t| " + grade.getGrade(courseId) + "\t|");
        }

        System.out.println("-----------------------");
        System.out.println("平均分：" + grade.getAverage());
    }
}

使用时，可以通过调用 `ZSStudentManagerSystem.run()` 运行程序。
