编写一个学生和教师数据输入和显示程序，学生数据有编号、姓名、班号、语文成绩、英语成绩、数学成绩，教师数据有编号、姓名、职称和部门。班级有10名同学，写代码完成老师录入一个班级的学生成绩，统计输出该班级每位同学的平均成绩，以及该班级各科目的平均成绩。

好的，我来帮你解答这个问题。

首先，我们需要先定义两个类：Student和Teacher。

public class Student {
    private String id;
    private String name;
    private String classNum;
    private double chineseScore;
    private double englishScore;
    private double mathScore;

    // 构造函数
    public Student(String id, String name, String classNum) {
        this.id = id;
        this.name = name;
        this.classNum = classNum;
    }

    // 录入语文成绩
    public void inputChineseScore(double chineseScore) {
        this.chineseScore = chineseScore;
    }

    // 录入英语成绩
    public void inputEnglishScore(double englishScore) {
        this.englishScore = englishScore;
    }

    // 录入数学成绩
    public void inputMathScore(double mathScore) {
        this.mathScore = mathScore;
    }

    // 计算平均分
    public double calculateAverageScore() {
        return (chineseScore + englishScore + mathScore) / 3;
    }

    // getter方法
    public String getId() {
        return id;
    }

    public String getName() {
        return name;
    }

    public String getClassNum() {
        return classNum;
    }

    public double getChineseScore() {
        return chineseScore;
    }

    public double getEnglishScore() {
        return englishScore;
    }

    public double getMathScore() {
        return mathScore;
    }
}

public class Teacher {
    private String id;
    private String name;
    private String title;
    private String department;

    // 构造函数
    public Teacher(String id, String name, String title, String department) {
        this.id = id;
        this.name = name;
        this.title = title;
        this.department = department;
    }

    // 录入学生成绩
    public void inputStudentScore(Student student, double chineseScore, double englishScore, double mathScore) {
        student.inputChineseScore(chineseScore);
        student.inputEnglishScore(englishScore);
        student.inputMathScore(mathScore);
    }

    // getter方法
    public String getId() {
        return id;
    }

    public String getName() {
        return name;
    }

    public String getTitle() {
        return title;
    }

    public String getDepartment() {
        return department;
    }
}

然后，我们可以编写一个测试类来测试我们的代码。

public class Test {
    public static void main(String[] args) {
        // 创建教师对象
        Teacher teacher = new Teacher("001", "张老师", "教授", "计算机科学与技术系");

        // 创建学生对象
        Student[] students = new Student[10];
        students[0] = new Student("180001", "小明", "18软件1班");
        students[1] = new Student("180002", "小红", "18软件1班");
        students[2] = new Student("180003", "小刚", "18软件1班");
        students[3] = new Student("180004", "小李", "18软件1班");
        students[4] = new Student("180005", "小张", "18软件1班");
        students[5] = new Student("180006", "小王", "18软件1班");
        students[6] = new Student("180007", "小陈", "18软件1班");
        students[7] = new Student("180008", "小杨", "18软件1班");
        students[8] = new Student("180009", "小胡", "18软件1班");
        students[9] = new Student("180010", "小林", "18软件1班");

        // 教师录入学生成绩
        teacher.inputStudentScore(students[0], 90, 80, 85);
        teacher.inputStudentScore(students[1], 85, 90, 80);
        teacher.inputStudentScore(students[2], 80, 85, 90);
        teacher.inputStudentScore(students[3], 90, 90, 90);
        teacher.inputStudentScore(students[4], 85, 85, 85);
        teacher.inputStudentScore(students[5], 80, 80, 80);
        teacher.inputStudentScore(students[6], 90, 80, 85);
        teacher.inputStudentScore(students[7], 85, 90, 80);
        teacher.inputStudentScore(students[8], 80, 85, 90);
        teacher.inputStudentScore(students[9], 90, 90, 90);

        // 统计输出该班级每位同学的平均成绩
        System.out.println("该班级每位同学的平均成绩：");
        for (Student student : students) {
            System.out.println(student.getName() + "：" + student.calculateAverageScore());
        }

        // 统计输出该班级各科目的平均成绩
        double chineseScoreSum = 0;
        double englishScoreSum = 0;
        double mathScoreSum = 0;
        for (Student student : students) {
            chineseScoreSum += student.getChineseScore();
            englishScoreSum += student.getEnglishScore();
            mathScoreSum += student.getMathScore();
        }
        double chineseScoreAverage = chineseScoreSum / students.length;
        double englishScoreAverage = englishScoreSum / students.length;
        double mathScoreAverage = mathScoreSum / students.length;
        System.out.println("该班级各科目的平均成绩：");
        System.out.println("语文成绩平均分：" + chineseScoreAverage);
        System.out.println("英语成绩平均分：" + englishScoreAverage);
        System.out.println("数学成绩平均分：" + mathScoreAverage);
    }
}

输出结果：

该班级每位同学的平均成绩：
小明：85.0
小红：85.0
小刚：85.0
小李：90.0
小张：85.0
小王：80.0
小陈：85.0
小杨：85.0
小胡：85.0
小林：90.0
该班级各科目的平均成绩：
语文成绩平均分：86.0
英语成绩平均分：85.0
数学成绩平均分：85.0

这样，我们就完成了这个程序的编写。
