用java语言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，这是一个比较典型的CRUD操作，我们可以使用Java的面向对象编程语言来实现这个简单的学校人事管理系统。

首先，我们需要定义一个基本的人员信息类Person，包含编号、姓名、性别和出生日期等属性：

public class Person {
    private String id;        // 编号
    private String name;      // 姓名
    private String gender;    // 性别
    private String birthday;  // 出生日期
    
    // 构造函数
    public Person(String id, String name, String gender, String birthday) {
        this.id = id;
        this.name = name;
        this.gender = gender;
        this.birthday = birthday;
    }
    
    // getter和setter方法
    public String getId() {
        return id;
    }
    public void setId(String 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 String getBirthday() {
        return birthday;
    }
    public void setBirthday(String birthday) {
        this.birthday = birthday;
    }
}

接着，我们定义教师类Teacher和学生类Student，继承自Person类，并添加各自独有的属性：

public class Teacher extends Person {
    private String department;  // 部门
    private String title;       // 职称
    private double salary;      // 工资
    
    // 构造函数
    public Teacher(String id, String name, String gender, String birthday, String department, String title, double salary) {
        super(id, name, gender, birthday);
        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 double getSalary() {
        return salary;
    }
    public void setSalary(double salary) {
        this.salary = salary;
    }
}

public class Student extends Person {
    private double score;    // 高考分数
    private String field;    // 专业
    private String className;  // 班级
    
    // 构造函数
    public Student(String id, String name, String gender, String birthday, double score, String field, String className) {
        super(id, name, gender, birthday);
        this.score = score;
        this.field = field;
        this.className = className;
    }
    
    // getter和setter方法
    public double getScore() {
        return score;
    }
    public void setScore(double score) {
        this.score = score;
    }
    public String getField() {
        return field;
    }
    public void setField(String field) {
        this.field = field;
    }
    public String getClassName() {
        return className;
    }
    public void setClassName(String className) {
        this.className = className;
    }
}

现在，我们可以定义一个管理系统类SchoolManagementSystem，用来实现教师和学生信息的添加、删除、修改和查询功能：

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

public class SchoolManagementSystem {
    private List<Teacher> teachers;  // 教师列表
    private List<Student> students;  // 学生列表
    
    // 构造函数
    public SchoolManagementSystem() {
        this.teachers = new ArrayList<>();
        this.students = new ArrayList<>();
    }
    
    // 添加教师信息
    public void addTeacher(Teacher teacher) {
        this.teachers.add(teacher);
    }
    
    // 删除教师信息
    public void deleteTeacher(String id) {
        Teacher teacher = findTeacherById(id);
        if (teacher != null) {
            this.teachers.remove(teacher);
        }
    }
    
    // 修改教师信息
    public void updateTeacher(Teacher teacher) {
        Teacher oldTeacher = findTeacherById(teacher.getId());
        if (oldTeacher != null) {
            oldTeacher.setName(teacher.getName());
            oldTeacher.setGender(teacher.getGender());
            oldTeacher.setBirthday(teacher.getBirthday());
            oldTeacher.setDepartment(teacher.getDepartment());
            oldTeacher.setTitle(teacher.getTitle());
            oldTeacher.setSalary(teacher.getSalary());
        }
    }
    
    // 查询教师信息
    public List<Teacher> findTeachers(String keyword) {
        List<Teacher> result = new ArrayList<>();
        for (Teacher teacher : this.teachers) {
            if (teacher.getName().contains(keyword) || teacher.getId().equals(keyword)) {
                result.add(teacher);
            }
        }
        return result;
    }
    
    // 根据id查找教师
    private Teacher findTeacherById(String id) {
        for (Teacher teacher : this.teachers) {
            if (teacher.getId().equals(id)) {
                return teacher;
            }
        }
        return null;
    }
    
    // 添加学生信息
    public void addStudent(Student student) {
        this.students.add(student);
    }
    
    // 删除学生信息
    public void deleteStudent(String id) {
        Student student = findStudentById(id);
        if (student != null) {
            this.students.remove(student);
        }
    }
    
    // 修改学生信息
    public void updateStudent(Student student) {
        Student oldStudent = findStudentById(student.getId());
        if (oldStudent != null) {
            oldStudent.setName(student.getName());
            oldStudent.setGender(student.getGender());
            oldStudent.setBirthday(student.getBirthday());
            oldStudent.setScore(student.getScore());
            oldStudent.setField(student.getField());
            oldStudent.setClassName(student.getClassName());
        }
    }
    
    // 查询学生信息
    public List<Student> findStudents(String keyword) {
        List<Student> result = new ArrayList<>();
        for (Student student : this.students) {
            if (student.getName().contains(keyword) || student.getId().equals(keyword)) {
                result.add(student);
            }
        }
        return result;
    }
    
    // 根据id查找学生
    private Student findStudentById(String id) {
        for (Student student : this.students) {
            if (student.getId().equals(id)) {
                return student;
            }
        }
        return null;
    }
}

现在我们已经定义了一个简单的学校人事管理系统，可以进行教师和学生信息的添加、删除、修改和查询操作。当然，这只是一个最基本的实现方式，还可以根据实际需求进行更多的功能扩展和优化。
