java.设计一个简单的学校人事管理系统,管理教师和学生信息。实现教师与学生基本信息的添加、删除、修改、查询。其中编号、姓名、性别、出生日期为共有的，教师包括部门、职称、工资；学生包括高考分数、专业field、班级等。

好的，这个学校人事管理系统可以使用面向对象的思想进行设计和实现。首先我们可以定义两个类：Teacher和Student，它们都包含编号、姓名、性别、出生日期这些共有的属性，并分别包含教师和学生特有的属性。

代码示例：

public class Person {
    private int id; // 编号
    private String name; // 姓名
    private String gender; // 性别
    private Date birthdate; // 出生日期
    
    // 构造函数
    public Person(int id, String name, String gender, Date birthdate) {
        this.id = id;
        this.name = name;
        this.gender = gender;
        this.birthdate = birthdate;
    }
    
    // getter和setter方法
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getGender() {
        return gender;
    }
    public void setGender(String gender) {
        this.gender = gender;
    }
    public Date getBirthdate() {
        return birthdate;
    }
    public void setBirthdate(Date birthdate) {
        this.birthdate = birthdate;
    }
}

public class Teacher extends Person {
    private String department; // 部门
    private String title; // 职称
    private int salary; // 工资
    
    // 构造函数
    public Teacher(int id, String name, String gender, Date birthdate, 
                   String department, String title, int salary) {
        super(id, name, gender, birthdate);
        this.department = department;
        this.title = title;
        this.salary = salary;
    }
    
    // getter和setter方法
    public String getDepartment() {
        return department;
    }
    public void setDepartment(String department) {
        this.department = department;
    }
    public String getTitle() {
        return title;
    }
    public void setTitle(String title) {
        this.title = title;
    }
    public int getSalary() {
        return salary;
    }
    public void setSalary(int salary) {
        this.salary = salary;
    }
}

public class Student extends Person {
    private int score; // 高考分数
    private String field; // 专业
    private String clazz; // 班级
    
    // 构造函数
    public Student(int id, String name, String gender, Date birthdate, 
                   int score, String field, String clazz) {
        super(id, name, gender, birthdate);
        this.score = score;
        this.field = field;
        this.clazz = clazz;
    }
    
    // getter和setter方法
    public int getScore() {
        return score;
    }
    public void setScore(int score) {
        this.score = score;
    }
    public String getField() {
        return field;
    }
    public void setField(String field) {
        this.field = field;
    }
    public String getClazz() {
        return clazz;
    }
    public void setClazz(String clazz) {
        this.clazz = clazz;
    }
}

接下来，我们可以定义一个管理类SchoolManagementSystem，它包含一个教师列表和一个学生列表，以及对它们进行添加、删除、修改、查询的方法。

代码示例：

import java.util.ArrayList;
import java.util.List;

public class SchoolManagementSystem {
    private List<Teacher> teacherList; // 教师列表
    private List<Student> studentList; // 学生列表
    
    // 构造函数
    public SchoolManagementSystem() {
        this.teacherList = new ArrayList<Teacher>();
        this.studentList = new ArrayList<Student>();
    }
    
    // 添加教师
    public void addTeacher(Teacher teacher) {
        teacherList.add(teacher);
    }
    
    // 删除教师
    public void removeTeacher(int id) {
        for (Teacher teacher : teacherList) {
            if (teacher.getId() == id) {
                teacherList.remove(teacher);
                break;
            }
        }
    }
    
    // 修改教师
    public void updateTeacher(Teacher teacher) {
        for (int i = 0; i < teacherList.size(); i++) {
            if (teacherList.get(i).getId() == teacher.getId()) {
                teacherList.set(i, teacher);
                break;
            }
        }
    }
    
    // 查询教师
    public Teacher queryTeacher(int id) {
        for (Teacher teacher : teacherList) {
            if (teacher.getId() == id) {
                return teacher;
            }
        }
        return null;
    }
    
    // 添加学生
    public void addStudent(Student student) {
        studentList.add(student);
    }
    
    // 删除学生
    public void removeStudent(int id) {
        for (Student student : studentList) {
            if (student.getId() == id) {
                studentList.remove(student);
                break;
            }
        }
    }
    
    // 修改学生
    public void updateStudent(Student student) {
        for (int i = 0; i < studentList.size(); i++) {
            if (studentList.get(i).getId() == student.getId()) {
                studentList.set(i, student);
                break;
            }
        }
    }
    
    // 查询学生
    public Student queryStudent(int id) {
        for (Student student : studentList) {
            if (student.getId() == id) {
                return student;
            }
        }
        return null;
    }
}

这样，我们就完成了一个简单的学校人事管理系统，可以对教师和学生的基本信息进行添加、删除、修改、查询。当然，实际的系统还需要一些其他的功能，例如输入输出、数据存储等，这里就不做详细说明了。
