用java写一个医生信息管理系统

好的，我可以为您提供一个简单的医生信息管理系统的Java代码示例。该系统可以实现添加、删除、修改和查找医生信息的功能。

首先，我们需要创建一个Doctor类来定义医生的属性和方法，如下所示：

public class Doctor {
    private int id;
    private String name;
    private String department;
    private String title;
    private String phone;

    public Doctor(int id, String name, String department, String title, String phone) {
        this.id = id;
        this.name = name;
        this.department = department;
        this.title = title;
        this.phone = phone;
    }

    public int getId() {
        return id;
    }

    public String getName() {
        return name;
    }

    public String getDepartment() {
        return department;
    }

    public String getTitle() {
        return title;
    }

    public String getPhone() {
        return phone;
    }

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

    public void setDepartment(String department) {
        this.department = department;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }

    @Override
    public String toString() {
        return "Doctor{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", department='" + department + '\'' +
                ", title='" + title + '\'' +
                ", phone='" + phone + '\'' +
                '}';
    }
}

然后，我们需要创建一个DoctorManager类来管理医生信息，如下所示：

import java.util.ArrayList;

public class DoctorManager {
    private ArrayList<Doctor> doctors;

    public DoctorManager() {
        doctors = new ArrayList<>();
    }

    public void addDoctor(Doctor doctor) {
        doctors.add(doctor);
    }

    public void removeDoctor(int id) {
        for (Doctor doctor : doctors) {
            if (doctor.getId() == id) {
                doctors.remove(doctor);
                break;
            }
        }
    }

    public Doctor findDoctor(int id) {
        for (Doctor doctor : doctors) {
            if (doctor.getId() == id) {
                return doctor;
            }
        }
        return null;
    }

    public void updateDoctor(Doctor doctor) {
        int index = doctors.indexOf(doctor);
        if (index != -1) {
            doctors.set(index, doctor);
        }
    }

    public ArrayList<Doctor> getAllDoctors() {
        return doctors;
    }
}

最后，我们可以创建一个DoctorTest类来测试DoctorManager类，如下所示：

public class DoctorTest {
    public static void main(String[] args) {
        DoctorManager manager = new DoctorManager();

        Doctor doctor1 = new Doctor(1, "张三", "内科", "主治医师", "13812345678");
        Doctor doctor2 = new Doctor(2, "李四", "外科", "副主任医师", "13912345678");
        Doctor doctor3 = new Doctor(3, "王五", "口腔科", "医师", "13612345678");

        manager.addDoctor(doctor1);
        manager.addDoctor(doctor2);
        manager.addDoctor(doctor3);

        System.out.println("所有医生信息：");
        for (Doctor doctor : manager.getAllDoctors()) {
            System.out.println(doctor);
        }

        System.out.println("查找医生信息：");
        System.out.println(manager.findDoctor(2));

        System.out.println("修改医生信息：");
        Doctor doctor4 = new Doctor(2, "赵六", "外科", "主任医师", "13987654321");
        manager.updateDoctor(doctor4);
        System.out.println(manager.findDoctor(2));

        System.out.println("删除医生信息：");
        manager.removeDoctor(3);
        for (Doctor doctor : manager.getAllDoctors()) {
            System.out.println(doctor);
        }
    }
}

以上就是一个简单的医生信息管理系统的Java代码示例。您可以根据需要进行修改和扩展。
