用java写一个教师管理系统

教师管理系统可以包括如下功能：

1. 添加、修改、删除教师信息；
2. 查询、排序、筛选教师信息；
3. 统计教师总数、男女比例、教学年限等信息；
4. 记录教师的考勤、请假、奖惩等情况；
5. 自动生成教师工资单；
6. 对教师进行评价和考核。

下面是一个简单的教师管理系统的 Java 代码示例：

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

public class TeacherManagementSystem {
    private List<Teacher> teachers = new ArrayList<>();

    public void addTeacher() {
        Scanner scanner = new Scanner(System.in);
        System.out.println("请输入教师姓名：");
        String name = scanner.nextLine();
        System.out.println("请输入教师性别：");
        String gender = scanner.nextLine();
        System.out.println("请输入教师年龄：");
        int age = scanner.nextInt();
        System.out.println("请输入教师工号：");
        int id = scanner.nextInt();
        System.out.println("请输入教师教龄：");
        int teachingYears = scanner.nextInt();
        System.out.println("请输入教师基本工资：");
        double baseSalary = scanner.nextDouble();
        Teacher teacher = new Teacher(name, gender, age, id, teachingYears, baseSalary);
        teachers.add(teacher);
        System.out.println("添加成功！");
    }

    public void deleteTeacher() {
        Scanner scanner = new Scanner(System.in);
        System.out.println("请输入要删除的教师工号：");
        int id = scanner.nextInt();
        for (int i = 0; i < teachers.size(); i++) {
            if (teachers.get(i).getId() == id) {
                teachers.remove(i);
                System.out.println("删除成功！");
                return;
            }
