java实现员工信息的增删改查

好的，这里提供一份基于Java的员工信息增删改查的示例代码。

首先，我们需要定义一个员工类，包含员工的基本信息：

public class Employee {
    private int id;
    private String name;
    private int age;
    private String gender;
    private String department;
    private String title;
    
    // 构造方法
    public Employee(int id, String name, int age, String gender, String department, String title) {
        this.id = id;
        this.name = name;
        this.age = age;
        this.gender = gender;
        this.department = department;
        this.title = title;
    }
    
    // getter和setter方法
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
    public String getGender() {
        return gender;
    }
    public void setGender(String gender) {
        this.gender = gender;
    }
    public String getDepartment() {
        return department;
    }
    public void setDepartment(String department) {
        this.department = department;
    }
    public String getTitle() {
        return title;
    }
    public void setTitle(String title) {
        this.title = title;
    }
}

接下来，我们需要定义一个员工信息管理类，包含增删改查的方法：

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

public class EmployeeManager {
    // 员工列表
    private List<Employee> employees = new ArrayList<>();
    
    // 增加员工
    public void addEmployee(Employee employee) {
        employees.add(employee);
    }
    
    // 删除员工
    public void deleteEmployee(int id) {
        for (Employee employee : employees) {
            if (employee.getId() == id) {
                employees.remove(employee);
                break;
            }
        }
    }
    
    // 修改员工信息
    public void updateEmployee(Employee employee) {
        for (int i = 0; i < employees.size(); i++) {
            if (employees.get(i).getId() == employee.getId()) {
                employees.set(i, employee);
                break;
            }
        }
    }
    
    // 查询员工信息
    public Employee getEmployee(int id) {
        for (Employee employee : employees) {
            if (employee.getId() == id) {
                return employee;
            }
        }
        return null;
    }
}

以上代码实现了基本的增删改查员工信息的功能，你可以根据具体需求进行修改和优化。同时，需要注意线程安全和异常处理等问题。
