编写java程序：创建有员工类，包括姓名、工号、性别、出生年月、家庭地址等。本系统能够按姓名或工号查找员工，并显示相关员工情况。包括：主控程序、员工档案管理子系统、员工类等。 其他要求： （1）实用，各模块自成系统 （2）完成最低要求：建立一个文件，包括同一个专业10个员工的必要信息，能对文件进行补充、修订、删除，并能进行查找。

以下是员工类的Java代码实现：

public class Employee {
    private String name;
    private int id;
    private String gender;
    private String birthDate;
    private String address;

    public Employee(String name, int id, String gender, String birthDate, String address) {
        this.name = name;
        this.id = id;
        this.gender = gender;
        this.birthDate = birthDate;
        this.address = address;
    }

    public String getName() {
        return name;
    }

    public int getId() {
        return id;
    }

    public String getGender() {
        return gender;
    }

    public String getBirthDate() {
        return birthDate;
    }

    public String getAddress() {
        return address;
    }
}

以下是员工档案管理子系统的Java代码实现：

import java.io.*;
import java.util.ArrayList;

public class EmployeeManagementSystem {
    private ArrayList<Employee> employees;
    private String fileName;

    public EmployeeManagementSystem(String fileName) {
        this.fileName = fileName;
        readFromFile();
    }

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

    public void deleteEmployeeById(int id) {
        for (Employee e : employees) {
            if (e.getId() == id) {
                employees.remove(e);
                break;
            }
        }
        writeToFile();
    }

    public Employee searchEmployeeByName(String name) {
        for (Employee e : employees) {
            if (e.getName().equals(name)) {
                return e;
            }
        }
        return null;
    }

    public Employee searchEmployeeById(int id) {
        for (Employee e : employees) {
            if (e.getId() == id) {
                return e;
            }
        }
        return null;
    }

    private void readFromFile() {
        employees = new ArrayList<>();
        try {
            BufferedReader br = new BufferedReader(new FileReader(fileName));
            String line;
            while ((line = br.readLine()) != null) {
                String[] data = line.split(",");
                String name = data[0];
                int id = Integer.parseInt(data[1]);
                String gender = data[2];
                String birthDate = data[3];
                String address = data[4];
                Employee employee = new Employee(name, id, gender, birthDate, address);
                employees.add(employee);
            }
            br.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    private void writeToFile() {
        try {
            BufferedWriter bw = new BufferedWriter(new FileWriter(fileName));
            for (Employee e : employees) {
                bw.write(e.getName() + "," + e.getId() + "," + e.getGender() + "," + e.getBirthDate() + "," + e.getAddress() + "\n");
            }
            bw.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

以下是主控程序的Java代码实现：

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        EmployeeManagementSystem ems = new EmployeeManagementSystem("employees.txt");
        Scanner scanner = new Scanner(System.in);
        while (true) {
            System.out.println("请选择您要进行的操作：");
            System.out.println("1. 添加员工");
            System.out.println("2. 删除员工");
            System.out.println("3. 按姓名查询员工");
            System.out.println("4. 按工号查询员工");
            System.out.println("0. 退出程序");
            int choice = scanner.nextInt();
            if (choice == 0) {
                break;
            }
            switch (choice) {
                case 1:
                    System.out.println("请输入员工姓名：");
                    String name = scanner.next();
                    System.out.println("请输入员工工号：");
                    int id = scanner.nextInt();
                    System.out.println("请输入员工性别：");
                    String gender = scanner.next();
                    System.out.println("请输入员工出生年月：");
                    String birthDate = scanner.next();
                    System.out.println("请输入员工家庭地址：");
                    String address = scanner.next();
                    Employee employee = new Employee(name, id, gender, birthDate, address);
                    ems.addEmployee(employee);
                    System.out.println("员工添加成功！");
                    break;
                case 2:
                    System.out.println("请输入员工工号：");
                    int deleteId = scanner.nextInt();
                    ems.deleteEmployeeById(deleteId);
                    System.out.println("员工删除成功！");
                    break;
                case 3:
                    System.out.println("请输入员工姓名：");
                    String searchName = scanner.next();
                    Employee e1 = ems.searchEmployeeByName(searchName);
                    if (e1 != null) {
                        System.out.println("姓名：" + e1.getName());
                        System.out.println("工号：" + e1.getId());
                        System.out.println("性别：" + e1.getGender());
                        System.out.println("出生年月：" + e1.getBirthDate());
                        System.out.println("家庭地址：" + e1.getAddress());
                    } else {
                        System.out.println("未找到该员工！");
                    }
                    break;
                case 4:
                    System.out.println("请输入员工工号：");
                    int searchId = scanner.nextInt();
                    Employee e2 = ems.searchEmployeeById(searchId);
                    if (e2 != null) {
                        System.out.println("姓名：" + e2.getName());
                        System.out.println("工号：" + e2.getId());
                        System.out.println("性别：" + e2.getGender());
                        System.out.println("出生年月：" + e2.getBirthDate());
                        System.out.println("家庭地址：" + e2.getAddress());
                    } else {
                        System.out.println("未找到该员工！");
                    }
                    break;
                default:
                    System.out.println("输入有误，请重新输入！");
            }
        }
    }
}

以上代码实现了一个简单的员工档案管理系统，可以进行员工的添加、删除、查找等操作，并将数据存储在文件中。
