java员工管理系统

Java员工管理系统是一个可以管理员工信息的系统，可以实现员工信息的增删改查等功能。根据提供的引用内容，可以建立一个员工类，包含员工的工号、姓名、年龄、性别和专业属性。同时，可以使用动态数组来存储员工信息，实现对员工信息的管理。

以下是一个简单的Java员工管理系统的示例代码：

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

public class EmployeeManagementSystem {
    private ArrayList<Staff> staffList;

    public EmployeeManagementSystem() {
        staffList = new ArrayList<>();
    }

    public void addStaff(Staff staff) {
        staffList.add(staff);
    }

    public void deleteStaff(int id) {
        for (Staff staff : staffList) {
            if (staff.getId() == id) {
                staffList.remove(staff);
                break;
            }
        }
    }

    public void updateStaff(Staff staff) {
        for (Staff s : staffList) {
            if (s.getId() == staff.getId()) {
                s.setName(staff.getName());
                s.setAge(staff.getAge());
                s.setSex(staff.getSex());
                s.setSpecialty(staff.getSpecialty());
                break;
            }
        }
    }

    public void searchStaff(int id) {
        for (Staff staff : staffList) {
            if (staff.getId() == id) {
                System.out.println(staff);
                break;
            }
        }
    }

    public void displayAllStaff() {
        for (Staff staff : staffList) {
            System.out.println(staff);
        }
    }

    public static void main(String[] args) {
        EmployeeManagementSystem ems = new EmployeeManagementSystem();
        Scanner scanner = new Scanner(System.in);
        while (true) {
            System.out.println("请选择操作：1.添加员工 2.删除员工 3.修改员工信息 4.查询员工信息 5.显示所有员工信息 6.退出");
            int choice = scanner.nextInt();
            switch (choice) {
                case 1:
                    System.out.println("请输入员工信息：");
                    System.out.print("工号：");
                    int id = scanner.nextInt();
                    System.out.print("姓名：");
                    String name = scanner.next();
                    System.out.print("年龄：");
                    int age = scanner.nextInt();

                    Staff staff = new Staff(id, name, age, sex, specialty);
                    ems.addStaff(staff);
                    System.out.println("添加成功！");
                    break;
                case 2:
                    System.out.print("请输入要删除的员工工号：");
                    int deleteId = scanner.nextInt();
                    ems.deleteStaff(deleteId);
                    System.out.println("删除成功！");
                    break;
                case 3:

                    break;
                case 4:

                    int searchId = scanner.nextInt();
                    ems.searchStaff(searchId);
                    break;
                case 5:
