java程序设计：员工管理系统

以下是一个简单的Java员工管理系统的示例：

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

class Employee {
    private String name;
    private int age;
    private String position;

    public Employee(String name, int age, String position) {
        this.name = name;
        this.age = age;
        this.position = position;
    }

    public String getName() {
        return name;
    }

    public int getAge() {
        return age;
    }

    public String getPosition() {
        return position;
    }
}

class EmployeeManagementSystem {
    private List<Employee> employees;

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

    public void addEmployee(Employee employee) {
        employees.add(employee);
    }

    public void removeEmployee(Employee employee) {
        employees.remove(employee);
    }

    public void displayEmployees() {
        for (Employee employee : employees) {
            System.out.println("Name: " + employee.getName());
            System.out.println("Age: " + employee.getAge());
            System.out.println("Position: " + employee.getPosition());
            System.out.println("--");
        }
    }
}

public class Main {
    public static void main(String[] args) {
        EmployeeManagementSystem system = new EmployeeManagementSystem();
        Scanner scanner = new Scanner(System.in);

        while (true) {
            System.out.println("1. Add Employee");
            System.out.println("2. Remove Employee");
            System.out.println("3. Display Employees");
            System.out.println("4. Exit");
            System.out.print("Enter your choice: ");
            int choice = scanner.nextInt();

            switch (choice) {
                case 1:
                    System.out.print("Enter employee name: ");
                    String name = scanner.next();
                    System.out.print("Enter employee age: ");
                    int age = scanner.nextInt();
                    System.out.print("Enter employee position: ");
                    String position = scanner.next();
                    Employee employee = new Employee(name, age, position);
                    system.addEmployee(employee);
                    System.out.println("Employee added successfully!");
                    break;
                case 2:
                    System.out.print("Enter employee name to remove: ");
                    String nameToRemove = scanner.next();
                    Employee employeeToRemove = null;
                    for (Employee emp : system.getEmployees()) {
                        if (emp.getName().equals(nameToRemove)) {
                            employeeToRemove = emp;
                            break;
                        }
                    }
                    if (employeeToRemove != null) {
                        system.removeEmployee(employeeToRemove);
                        System.out.println("Employee removed successfully!");
                    } else {
                        System.out.println("Employee not found!");
                    }
                    break;
                case 3:
                    system.displayEmployees();
                    break;
                case 4:
                    System.exit(0);
                    break;
                default:
                    System.out.println("Invalid choice!");
            }
        }
    }
}

这个程序实现了一个简单的员工管理系统，可以添加、删除和显示员工信息。用户可以通过控制台菜单选择不同的操作。你可以根据自己的需求进行扩展和修改。
