用java 写一个职工工资管理系统的代码要求为相关信息包括有：职工号、姓名、月工资、岗位、年龄、性别等信息。 系统要求实现如下功能： 1）系统功能以菜单方式工作（用Swing设计界面）； 2）数据的输入； 3）职工信息数据修改； 4）数据的列表展示； 5）数据的删除； 6）数据的查找，通常以两种方式进行查找，如姓名、记录号（或学号、职工号等）； 7）退出系统。

好的，下面是一个简单的职工工资管理系统的Java代码示例，实现了您提到的功能：

import java.util.ArrayList;
import javax.swing.*;
import javax.swing.table.DefaultTableModel;

public class EmployeeSalarySystem {
    private ArrayList<Employee> employeeList;

    public int getAge() {
        return age;
    }

    public String getGender() {

}

这个示例代码使用了Swing库来实现窗口界面和交互，使用了JTable来显示职工数据列表。您可以根据需要对代码进行修改和完善。
