用Java实现在学校的人事管理系统中，应该包含对教师与学生的基本信息管理。其中有些信息是教师与学生共同拥有的，例如编号、姓名、性别、出生日期等；而有些信息则是教师、学生特有的，例如教师应该包括所在部门、职称、工资等；学生应该包含高考分数、所学专业等。为此，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TeacherClass和学生类StudentClass等子类。最后编写含main函数的主类，测试该程序中各个类是否可用（代码可自行定义，达到目的即可）。

好的，我理解了你的问题。以下是Java实现的示例代码，包括PersonClass、TeacherClass、StudentClass和测试主类：

// PersonClass.java
public class PersonClass {
    private int id;
    private String name;
    private String gender;
    private String birthdate;
    
    public PersonClass(int id, String name, String gender, String birthdate) {
        this.id = id;
        this.name = name;
        this.gender = gender;
        this.birthdate = birthdate;
    }
    
    public int getId() {
        return id;
    }
    
    public String getName() {
        return name;
    }
    
    public String getGender() {
        return gender;
    }
    
    public String getBirthdate() {
        return birthdate;
    }
}

// TeacherClass.java
public class TeacherClass extends PersonClass {
    private String department;
    private String title;
    private double salary;
    
    public TeacherClass(int id, String name, String gender, String birthdate, String department, String title, double salary) {
        super(id, name, gender, birthdate);
        this.department = department;
        this.title = title;
        this.salary = salary;
    }
    
    public String getDepartment() {
        return department;
    }
    
    public String getTitle() {
        return title;
    }
    
    public double getSalary() {
        return salary;
    }
}

// StudentClass.java
public class StudentClass extends PersonClass {
    private int examScore;
    private String major;
    
    public StudentClass(int id, String name, String gender, String birthdate, int examScore, String major) {
        super(id, name, gender, birthdate);
        this.examScore = examScore;
        this.major = major;
    }
    
    public int getExamScore() {
        return examScore;
    }
    
    public String getMajor() {
        return major;
    }
}

// MainClass.java
public class MainClass {
    public static void main(String[] args) {
        TeacherClass teacher = new TeacherClass(1001, "张三", "男", "1990-01-01", "计算机科学与技术", "副教授", 8000.0);
        StudentClass student = new StudentClass(2001, "李四", "女", "2000-01-01", 600, "软件工程");
        
        System.out.println("教师信息：");
        System.out.println("编号：" + teacher.getId());
        System.out.println("姓名：" + teacher.getName());
        System.out.println("性别：" + teacher.getGender());
        System.out.println("出生日期：" + teacher.getBirthdate());
        System.out.println("所在部门：" + teacher.getDepartment());
        System.out.println("职称：" + teacher.getTitle());
        System.out.println("工资：" + teacher.getSalary());
        
        System.out.println("学生信息：");
        System.out.println("编号：" + student.getId());
        System.out.println("姓名：" + student.getName());
        System.out.println("性别：" + student.getGender());
        System.out.println("出生日期：" + student.getBirthdate());
        System.out.println("高考分数：" + student.getExamScore());
        System.out.println("所学专业：" + student.getMajor());
    }
}

在这个示例中，我们定义了PersonClass作为父类，包含编号、姓名、性别、出生日期等基本信息。然后定义了TeacherClass和StudentClass作为PersonClass的子类，分别包含教师和学生特有的信息。最后在MainClass中测试了各个类的可用性。当我们运行MainClass时，将输出教师和学生的信息。

希望这个示例能够帮助到你！
