职工信息管理系统java

以下是一个简单的职工信息管理系统的Java代码示例，它可以添加、删除、修改和查找职工信息：

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

public class EmployeeManagementSystem {
    private ArrayList<Employee> employees = new ArrayList<Employee>();
    private Scanner scanner = new Scanner(System.in);

    public void start() {
        while (true) {
            System.out.println("请选择操作：");
            System.out.println("1. 添加职工信息");
            System.out.println("2. 删除职工信息");
            System.out.println("3. 修改职工信息");
            System.out.println("4. 查找职工信息");
            System.out.println("5. 退出系统");

            int choice = scanner.nextInt();
            switch (choice) {
                case 1:
                    addEmployee();
                    break;
                case 2:
                    deleteEmployee();
                    break;
                case 3:
                    updateEmployee();
                    break;
                case 4:

                    break;
                case 5:
                    System.out.println("谢谢使用！");
                    System.exit(0);
                    break;

        String position = scanner.next();

        employees.add(employee);
        System.out.println("添加成功！");
    }
