用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。文字步骤详细。

好的，我可以为您提供一个简单的学校人事管理系统的设计，使用Java语言实现。

1. 首先，我们需要设计一个Person类，作为教师和学生类的父类，其中包含编号、姓名、性别和出生日期等共有属性，代码如下：

public class Person {
    private int id;
    private String name;
    private String gender;
    private String birthdate;
    
    public Person(int id, String name, String gender, String birthdate) {
        this.id = id;
        this.name = name;
        this.gender = gender;
        this.birthdate = birthdate;
    }
    
    // getter and setter methods
}

2. 接下来，我们需要设计一个Teacher类，继承自Person类，包括部门、职称和工资等属性，代码如下：

public class Teacher extends Person {
    private String department;
    private String title;
    private double salary;
    
    public Teacher(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;
    }
    
    // getter and setter methods
}

3. 再设计一个Student类，同样继承自Person类，包括高考分数、专业和班级等属性，代码如下：

public class Student extends Person {
    private int score;
    private String field;
    private String className;
    
    public Student(int id, String name, String gender, String birthdate, int score, String field, String className) {
        super(id, name, gender, birthdate);
        this.score = score;
        this.field = field;
        this.className = className;
    }
    
    // getter and setter methods
}

4. 接下来，我们需要设计一个管理类，用于实现教师和学生信息的添加、删除、修改和查询功能，代码如下：

import java.util.ArrayList;

public class Management {
    private ArrayList<Teacher> teacherList;
    private ArrayList<Student> studentList;
    
    public Management() {
        teacherList = new ArrayList<Teacher>();
        studentList = new ArrayList<Student>();
    }
    
    // 添加教师
    public void addTeacher(Teacher teacher) {
        teacherList.add(teacher);
    }
    
    // 删除教师
    public void deleteTeacher(int id) {
        for (Teacher teacher : teacherList) {
            if (teacher.getId() == id) {
                teacherList.remove(teacher);
                break;
            }
        }
    }
    
    // 修改教师信息
    public void modifyTeacher(int id, String department, String title, double salary) {
        for (Teacher teacher : teacherList) {
            if (teacher.getId() == id) {
                teacher.setDepartment(department);
                teacher.setTitle(title);
                teacher.setSalary(salary);
                break;
            }
        }
    }
    
    // 查询教师信息
    public void queryTeacher(int id) {
        for (Teacher teacher : teacherList) {
            if (teacher.getId() == id) {
                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("部门：" + teacher.getDepartment());
                System.out.println("职称：" + teacher.getTitle());
                System.out.println("工资：" + teacher.getSalary());
                break;
            }
        }
    }
    
    // 添加学生
    public void addStudent(Student student) {
        studentList.add(student);
    }
    
    // 删除学生
    public void deleteStudent(int id) {
        for (Student student : studentList) {
            if (student.getId() == id) {
                studentList.remove(student);
                break;
            }
        }
    }
    
    // 修改学生信息
    public void modifyStudent(int id, int score, String field, String className) {
        for (Student student : studentList) {
            if (student.getId() == id) {
                student.setScore(score);
                student.setField(field);
                student.setClassName(className);
                break;
            }
        }
    }
    
    // 查询学生信息
    public void queryStudent(int id) {
        for (Student student : studentList) {
            if (student.getId() == id) {
                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.getScore());
                System.out.println("专业：" + student.getField());
                System.out.println("班级：" + student.getClassName());
                break;
            }
        }
    }
}

5. 最后，我们可以在主方法中测试管理类的功能：

public static void main(String[] args) {
    Management management = new Management();
    
    // 添加教师
    Teacher teacher1 = new Teacher(1, "Tom", "male", "1990-01-01", "Math", "Professor", 10000.0);
    Teacher teacher2 = new Teacher(2, "Jerry", "male", "1995-01-01", "English", "Lecturer", 8000.0);
    management.addTeacher(teacher1);
    management.addTeacher(teacher2);
    
    // 添加学生
    Student student1 = new Student(1001, "Alice", "female", "2000-01-01", 600, "Math", "Class A");
    Student student2 = new Student(1002, "Bob", "male", "2001-01-01", 550, "English", "Class B");
    management.addStudent(student1);
    management.addStudent(student2);
    
    // 修改教师信息
    management.modifyTeacher(1, "Physics", "Associate Professor", 9000.0);
    
    // 查询学生信息
    management.queryStudent(1001);
    
    // 删除教师
    management.deleteTeacher(2);
}

以上就是一个简单的学校人事管理系统的设计和实现，您可以根据实际需要进行修改和完善。
