编写java程序：创建有员工类，包括姓名、工号、性别、出生年月、家庭地址并生成一个员工文件。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。

好的，我可以提供一个Java代码示例来实现这个功能。以下是一个基本的实现代码：

Employee.java

public class Employee {
    private String name; // 姓名
    private String id; // 工号
    private String gender; // 性别
    private String birth; // 出生年月
    private String address; // 家庭地址

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

    // getter和setter方法
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getGender() {
        return gender;
    }

    public void setGender(String gender) {
        this.gender = gender;
    }

    public String getBirth() {
        return birth;
    }

    public void setBirth(String birth) {
        this.birth = birth;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    // toString方法，用于输出员工信息
    @Override
    public String toString() {
        return "姓名：" + name + " 工号：" + id + " 性别：" + gender + " 出生年月：" + birth + " 家庭地址：" + address;
    }
}

                    system.searchById(id);
                    break;
                case 6:
                    system.writeToFile("employees.txt"); // 将员工信息写入文件
                    System.out.println("程序已退出。");
                    return;
                default:
                    System.out.println("无效操作！");
                    break;
            }
        }
    }
}

在上述代码中，我们将员工信息存储在一个ArrayList中，并通过文件读写操作实现了持久化。程序启动时，会从文件中读取数据到ArrayList中，程序结束时，会将ArrayList中的数据写入文件。通过交互式的菜单，用户可以对员工信息进行增、删、改、查等操作。

注意：为了简单起见，本示例中没有进行输入数据的有效性检查，实际应用中应该进行适当的验证和防范，以确保程序的健壮性和安全性。
