1.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。 java实现

以下是一个简单的学校人事管理系统的Java实现，包括教师和学生的基本信息的添加、删除、修改和查询功能。

Teacher.java

public class Teacher {
    private int id;
    private String name;
    private String gender;
    private String birthDate;
    private String department;
    private String jobTitle;
    private int salary;
    
    public Teacher(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;
    }

    // getter and setter methods for all fields
}

Student.java

public class Student {
    private int id;
    private String name;
    private String gender;
    private String birthDate;
    private int entranceScore;
    private String field;
    private String className;
    
    public Student(int id, String name, String gender, String birthDate, int entranceScore, String field, String className) {
        this.id = id;
        this.name = name;
        this.gender = gender;
        this.birthDate = birthDate;
        this.entranceScore = entranceScore;
        this.field = field;
        this.className = className;
    }

    // getter and setter methods for all fields
}

SchoolManager.java

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

public class SchoolManager {
    private List<Teacher> teachers;
    private List<Student> students;
    
    public SchoolManager() {
        this.teachers = new ArrayList<Teacher>();
        this.students = new ArrayList<Student>();
    }
    
    // add a teacher
    public void addTeacher(int id, String name, String gender, String birthDate, String department, String jobTitle, int salary) {
        Teacher teacher = new Teacher(id, name, gender, birthDate, department, jobTitle, salary);
        this.teachers.add(teacher);
    }
    
    // add a student
    public void addStudent(int id, String name, String gender, String birthDate, int entranceScore, String field, String className) {
        Student student = new Student(id, name, gender, birthDate, entranceScore, field, className);
        this.students.add(student);
    }
    
    // delete a teacher by ID
    public void deleteTeacher(int id) {
        for (Teacher teacher : this.teachers) {
            if (teacher.getId() == id) {
                this.teachers.remove(teacher);
                break;
            }
        }
    }
    
    // delete a student by ID
    public void deleteStudent(int id) {
        for (Student student : this.students) {
            if (student.getId() == id) {
                this.students.remove(student);
                break;
            }
        }
    }
    
    // update the information of a teacher by ID
    public void updateTeacher(int id, String name, String gender, String birthDate, String department, String jobTitle, int salary) {
        for (Teacher teacher : this.teachers) {
            if (teacher.getId() == id) {
                teacher.setName(name);
                teacher.setGender(gender);
                teacher.setBirthDate(birthDate);
                teacher.setDepartment(department);
                teacher.setJobTitle(jobTitle);
                teacher.setSalary(salary);
                break;
            }
        }
    }
    
    // update the information of a student by ID
    public void updateStudent(int id, String name, String gender, String birthDate, int entranceScore, String field, String className) {
        for (Student student : this.students) {
            if (student.getId() == id) {
                student.setName(name);
                student.setGender(gender);
                student.setBirthDate(birthDate);
                student.setEntranceScore(entranceScore);
                student.setField(field);
                student.setClassName(className);
                break;
            }
        }
    }
    
    // search for a teacher by ID
    public Teacher searchTeacher(int id) {
        for (Teacher teacher : this.teachers) {
            if (teacher.getId() == id) {
                return teacher;
            }
        }
        return null;
    }
    
    // search for a student by ID
    public Student searchStudent(int id) {
        for (Student student : this.students) {
            if (student.getId() == id) {
                return student;
            }
        }
        return null;
    }
}

使用示例：

public class Main {
    public static void main(String[] args) {
        SchoolManager manager = new SchoolManager();
        
        // add a teacher
        manager.addTeacher(1, "John", "Male", "1990-01-01", "Mathematics", "Professor", 10000);
        
        // add a student
        manager.addStudent(1, "Amy", "Female", "2000-01-01", 600, "Computer Science", "Class A");
        
        // update the information of a teacher
        manager.updateTeacher(1, "John Smith", "Male", "1990-02-02", "Computer Science", "Associate Professor", 8000);
        
        // search for a student by ID
        Student student = manager.searchStudent(1);
        System.out.println(student.getName() + " " + student.getEntranceScore());
        
        // delete a teacher by ID
        manager.deleteTeacher(1);
    }
}
