题目如下:在学校的人事管理系统中，教师与学生共同拥有的信息为，编号、姓名、性别、出生日期等；教师特有的信息为所在部门、职称、工资等；学生特有信息为高考分数、所学专业，将教师与学生共同拥有的部分，定义为人员类PersonClass（作为父类），并在此基础上定义教师类TercharClass和学生类StudentClass两个子类。将父类PersonClass修改为接口，在子类教师类TercharClass和学生类StudentClass中实现接口。编写含main函数的主类，测试接口。请主意是测试接口，请写出代码

以下是Java代码示例：

// 定义PersonClass接口
interface PersonClass {
    public int getID(); // 获取编号
    public String getName(); // 获取姓名
    public String getGender(); // 获取性别
    public String getBirthDate(); // 获取出生日期
}

// 定义TercharClass类，实现PersonClass接口
class TercharClass implements PersonClass {
    private int id;
    private String name;
    private String gender;
    private String birthDate;
    private String department;
    private String jobTitle;
    private int salary;

    public TercharClass(int id, String name, String gender, String birthDate,
            String department, String jobTitle, int salary) {
        this.id = id;
        this.name = name;
        this.gender = gender;
        this.birthDate = birthDate;
        this.department = department;
        this.jobTitle = jobTitle;
        this.salary = salary;
    }

    // 实现PersonClass接口中的方法
    public int getID() {
        return id;
    }

    public String getName() {
        return name;
    }

    public String getGender() {
        return gender;
    }

    public String getBirthDate() {
        return birthDate;
    }

    // 获取所在部门
    public String getDepartment() {
        return department;
    }

    // 获取职称
    public String getJobTitle() {
        return jobTitle;
    }

    // 获取工资
    public int getSalary() {
        return salary;
    }
}

// 定义StudentClass类，实现PersonClass接口
class StudentClass implements PersonClass {
    private int id;
    private String name;
    private String gender;
    private String birthDate;
    private int examScore;
    private String major;

    public StudentClass(int id, String name, String gender, String birthDate,
            int examScore, String major) {
        this.id = id;
        this.name = name;
        this.gender = gender;
        this.birthDate = birthDate;
        this.examScore = examScore;
        this.major = major;
    }

    // 实现PersonClass接口中的方法
    public int getID() {
        return id;
    }

    public String getName() {
        return name;
    }

    public String getGender() {
        return gender;
    }

    public String getBirthDate() {
        return birthDate;
    }

    // 获取高考分数
    public int getExamScore() {
        return examScore;
    }

    // 获取所学专业
    public String getMajor() {
        return major;
    }
}

// 测试接口的主类
public class TestInterface {
    public static void main(String[] args) {
        // 创建一个教师对象
        TercharClass teacher = new TercharClass(1001, "张三", "男", "1980-01-01",
                "计算机科学与技术", "教授", 10000);
        // 创建一个学生对象
        StudentClass student = new StudentClass(2001, "李四", "女", "2000-01-01",
                600, "软件工程");

        // 调用接口中的方法获取共同信息
        System.out.println("教师编号：" + teacher.getID());
        System.out.println("教师姓名：" + teacher.getName());
        System.out.println("教师性别：" + teacher.getGender());
        System.out.println("教师出生日期：" + teacher.getBirthDate());

        System.out.println("学生编号：" + student.getID());
        System.out.println("学生姓名：" + student.getName());
        System.out.println("学生性别：" + student.getGender());
        System.out.println("学生出生日期：" + student.getBirthDate());

        // 调用教师类特有的方法
        System.out.println("教师所在部门：" + teacher.getDepartment());
        System.out.println("教师职称：" + teacher.getJobTitle());
        System.out.println("教师工资：" + teacher.getSalary());

        // 调用学生类特有的方法
        System.out.println("学生高考分数：" + student.getExamScore());
        System.out.println("学生所学专业：" + student.getMajor());
    }
}
