JAVA项目-------医院挂号系统

1，项目目的

1、科室管理：新增科室，删除科室（如果有医生在，则不能删除该科室），修改科室。
2、医生管理：录入医生信息，以及科室信息。修改医生信息（主要是修改个人信息和科室）
3、坐诊信息设置：可以设置医生当天和未来6天的坐诊情况，包括上午和下午的坐诊时间段和可预约数量，系统将自动保存到该医生的坐诊信息列表中。
4、全部信息展示：按照科室，展示每个医生七天的坐诊情况，需要按照科室归类展示
5、预约功能：用户可以选择要预约的科室，医生、日期和时间段，并输入患者的个人信息，系统将自动判断该时间段是否还有预约名额，并保存预约信息。
6.搜索功能：用户可以输入搜索日期和时间段，系统将自动搜索未来七天内在该时间段坐诊的医生信息，并按照科室分类展示。
7、可以查询某个医生未来七天，病人对它的预约情况。

2，建立一个部门类

package HostipalSystem;

import java.util.ArrayList;

public class department {
    private String name;
    ArrayList <doctor> doctors=new ArrayList<>();//医生列表

    public department() {
    }

    public department(String name, ArrayList<doctor> doctors) {
        this.name = name;
        this.doctors = doctors;
    }

    public String getName() {
        return name;
    }

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

    public ArrayList<doctor> getDoctors() {
        return doctors;
    }

    public void setDoctors(ArrayList<doctor> doctors) {
        this.doctors = doctors;
    }
}

3，医生类

package HostipalSystem;

import java.time.LocalDate;
import java.util.ArrayList;

public class doctor {
    private String name;
    private String sex;
    private int age;
    private String degree;
    private String advantage;
    private LocalDate jointime;
    private ArrayList<schedule> schedule;//一个医生7天的排版表
    private String department;
    private String id;
    public doctor() {
    }

    public String getDepartment() {
        return department;
    }

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

    public doctor(String name, String sex, int age, String degree, String advantage, LocalDate jointime, ArrayList<HostipalSystem.schedule> schedule, String id, String department) {
        this.name = name;
        this.sex = sex;
        this.age = age;
        this.degree = degree;
        this.advantage = advantage;
        this.jointime = jointime;
        this.schedule = schedule;
        this.id = id;
    }

    public String getId() {
        return id;
    }

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

    public String getName() {
        return name;
    }

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

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getDegree() {
        return degree;
    }

    public void setDegree(String degree) {
        this.degree = degree;
    }

    public String getAdvantage() {
        return advantage;
    }

    public void setAdvantage(String advantage) {
        this.advantage = advantage;
    }

    public LocalDate getJointime() {
        return jointime;
    }

    public void setJointime(LocalDate jointime) {
        this.jointime = jointime;
    }

    public ArrayList<HostipalSystem.schedule> getSchedule() {
        return schedule;
    }

    public void setSchedule(ArrayList<HostipalSystem.schedule> schedule) {
        this.schedule = schedule;
    }
}

4，排班类

主要是排班的信息

package HostipalSystem;

import java.time.LocalDate;
import java.time.LocalTime;

public class schedule {
    private LocalDate date;
    private String morning="N";
    private LocalTime starttime;
    private LocalTime endtime;
    private int numjiezhen;

        this.starttime = starttime;
        this.endtime = endtime;
        this.numjiezhen = numjiezhen;
        this.numyuyue = numyuyue;
        this.afternoon = afternoon;
        this.starttime1 = starttime1;
        this.endtime1 = endtime1;
        this.numjiezhen1 = numjiezhen1;
        this.numyuyue1 = numyuyue1;
        this.night = night;
        this.starttime2 = starttime2;
        this.endtime2 = endtime2;
        this.numjiezhen2 = numjiezhen2;
        this.numyuyue2 = numyuyue2;
    }

    public LocalDate getDate() {
        return date;
    }

    public void setDate(LocalDate date) {
        this.date = date;
    }

    public String getMorning() {
        return morning;
    }

    public void setMorning(String morning) {
        this.morning = morning;
    }

    public LocalTime getStarttime() {
        return starttime;
    }

    public void setStarttime(LocalTime starttime) {
        this.starttime = starttime;
    }

    public LocalTime getEndtime() {
        return endtime;
    }

    public void setEndtime(LocalTime endtime) {
        this.endtime = endtime;
    }

    public int getNumjiezhen() {
        return numjiezhen;
    }

    public void setNumjiezhen(int numjiezhen) {
        this.numjiezhen = numjiezhen;
    }

    public int getNumyuyue() {
        return numyuyue;
    }

    public void setNumyuyue(int numyuyue) {
        this.numyuyue = numyuyue;
    }

    public String getAfternoon() {
        return afternoon;
    }

    public void setAfternoon(String afternoon) {
        this.afternoon = afternoon;
    }

    public LocalTime getStarttime1() {
        return starttime1;
    }

    public void setStarttime1(LocalTime starttime1) {
        this.starttime1 = starttime1;
    }

    public LocalTime getEndtime1() {
        return endtime1;
    }

    public void setEndtime1(LocalTime endtime1) {
        this.endtime1 = endtime1;
    }

    public int getNumjiezhen1() {
        return numjiezhen1;
    }

    public void setNumjiezhen1(int numjiezhen1) {
        this.numjiezhen1 = numjiezhen1;
    }

    public int getNumyuyue1() {
        return numyuyue1;
    }

    public void setNumyuyue1(int numyuyue1) {
        this.numyuyue1 = numyuyue1;
    }

    public String getNight() {
        return night;
    }

    public void setNight(String night) {
        this.night = night;
    }

    public LocalTime getStarttime2() {
        return starttime2;
    }

    public void setStarttime2(LocalTime starttime2) {
        this.starttime2 = starttime2;
    }

    public LocalTime getEndtime2() {
        return endtime2;
    }

    public void setEndtime2(LocalTime endtime2) {
        this.endtime2 = endtime2;
    }

    public int getNumjiezhen2() {
        return numjiezhen2;
    }

    public void setNumjiezhen2(int numjiezhen2) {
        this.numjiezhen2 = numjiezhen2;
    }

    public int getNumyuyue2() {
        return numyuyue2;
    }

    public void setNumyuyue2(int numyuyue2) {
        this.numyuyue2 = numyuyue2;
    }
}

4，预约类

主要是病人的信息

package HostipalSystem;

import java.time.LocalDateTime;

public class oppintment {
    private  int num=0;
    private String name;
    private String sex;
    private int age;
    private String desc;
    private String doctor;
    private String departmentname;
    private LocalDateTime date;

    public oppintment() {
    }

    public int getNum() {
        return num;
    }

    public void setNum(int num) {
        this.num = num;
    }

    public oppintment(String name, String sex, int age, String desc, String doctor, String departmentname, LocalDateTime date, int num) {
        this.name = name;
        this.sex = sex;
        this.age = age;
        this.desc = desc;
        this.doctor = doctor;
        this.departmentname = departmentname;
        this.date = date;
        this.num=num;
    }

    public String getName() {
        return name;
    }

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

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getDesc() {
        return desc;
    }

    public void setDesc(String desc) {
        this.desc = desc;
    }

    public String getDoctor() {
        return doctor;
    }

    public void setDoctor(String doctor) {
        this.doctor = doctor;
    }

    public String getDepartmentname() {
        return departmentname;
    }

    public void setDepartmentname(String departmentname) {
        this.departmentname = departmentname;
    }

    public LocalDateTime getDate() {
        return date;
    }

    public void setDate(LocalDateTime date) {
        this.date = date;
    }
}

6，医院操着系统

6.1界面

public void start()
    {
        Boolean flag=true;
        while(flag)
        {
            Scanner sc= new Scanner(System.in);
            System.out.println("------------欢迎来到医院操作系统-------------");
            System.out.println("----------1,添加部门------------");
            System.out.println("----------2，添加医生------------");
            System.out.println("----------3，查询部门里的医生------------");
            System.out.println("----------4，查询医生的基本信息------------");
            System.out.println("----------5，查询可预约医生的时间------------");
            System.out.println("----------6，挂号------------");
            System.out.println("----------7，排班------------");
            System.out.println("----------8，退出操作系统------------");
            int command=sc.nextInt();
            switch (command)
            {
                case 1:
                    adddepasrtment();
                    break;
                case 2:
                    adddoctor();
                    break;
                case 3:
                    showdoctorindepartment();
                    break;
                case 4:
                    showdoctorinfo();
                    break;
                case 5:
                    showtimeofdoctor();
                    break;
                case 6:
                    booking();
                    break;
                case 8:
                    flag=false;
                    break;
                case 7:
                        operateschedule();
                        break;
                default:
                    System.out.println("输入有误，请重新输入");
            }
        }
    }

6.2设置部门

需要判断部门是否存在

public void adddepasrtment()
    {
        OUT:
        while(true)
        {
            department d=new department();
            Scanner sc=new Scanner(System.in);
            System.out.println("请输入你要添加的部门的名称");
            String name=sc.next();
            d.setName(name);
            for(int i=0;i<alldepartment.size();i++)
            {
                if(alldepartment.get(i).getName().equals(name))
                {
                    System.out.println("该部门已存在");
                    continue OUT;
                }
            }
            alldepartment.add(d);//将建好的部门添加进去
            break;
        }
    }

6.2.1遇到问题1

Scanner sc=new Scanner(System.in);
System.out.println("请输入你要添加的部门的名称");
String name=sc.next();

将以上输入语句放在外面，如果不合格将一直循环

错误代码如下：

public void adddepasrtment()
    {
        OUT:
        department d=new department();
        Scanner sc=new Scanner(System.in);
        System.out.println("请输入你要添加的部门的名称");
        String name=sc.next();
        while(true)
        {
            Scanner sc=new Scanner(System.in);
            System.out.println("请输入你要添加的部门的名称");
            String name=sc.next();
            d.setName(name);
            for(int i=0;i<alldepartment.size();i++)
            {
                if(alldepartment.get(i).getName().equals(name))
                {
                    System.out.println("该部门已存在");
                    continue OUT;
                }
            }
            alldepartment.add(d);
            break;
        }
    }

6.2.2遇到问题2

OUT:放在循环外面；

continue OUT放在循环里面结束一层循环

6.3建立一个存放部门的集合

ArrayList<department> alldepartment=new ArrayList<>();

7，医生的添加

public void adddoctor()
    {
        doctor d=new doctor();
        Scanner sc=new Scanner(System.in);
        System.out.println("请输入你要添加的医生的姓名");
        String name=sc.next();
        d.setName(name);
        System.out.println("请输入你要添加的医生的性别");
        String sex=sc.next();
        d.setSex(sex);
        System.out.println("请输入你要添加的医生的年龄");
        int age=sc.nextInt();
        d.setAge(age);
        System.out.println("请输入你要添加的医生的学历");
        String degree=sc.next();
        d.setDegree(degree);
        System.out.println("请输入你要添加的医生的擅长");
        String advantage=sc.next();
        d.setAdvantage(advantage);
        System.out.println("请输入你要添加的医生的入职时间");
        //LocalDate jointime=sc.nextLocalDate();
        d.setJointime(jointime());//调用方法存入医生的入职时间
        d.setId(UUID.randomUUID().toString());//生成随机数作为医生的编号
        System.out.println("您的编号是"+d.getId());
        System.out.println("请选择你的部门");
        for(int i=0;i<alldepartment.size();i++)
        {
            System.out.println(i+1+"."+alldepartment.get(i).getName());
        }
        while(true)
        {
            System.out.println("请输入部门的编号");
            int command=sc.nextInt();
            if(command>alldepartment.size()||command<1)
            {
                System.out.println("输入有误，请重新输入");
                continue;
            }
            else
            {
                d.setDepartment(alldepartment.get(command-1).getName());
                alldepartment.get(command-1).getDoctors().add(d);
                alldoctor.add(d);//将医生添加到科室里
                System.out.println("录入完毕");
                break;
            }
        }
    }

7.1医生的加入时间

public LocalDate jointime()
    {
        Scanner sc=new Scanner(System.in);
        System.out.println("请输入医生入职时间格式为yyyy-mm-dd");
        String jointime=sc.next();
        LocalDate date=LocalDate.parse(jointime);
        return date;
    }

7.2写一个集合存放所有医生

ArrayList<doctor> alldoctor=new ArrayList<>();

8,查询部门里的医生

public void showdoctorindepartment()
    {
        for(int i=0;i<alldepartment.size();i++)
        {
            System.out.println(i+1+"."+alldepartment.get(i).getName());
        }
        while(true)
        {
            System.out.println("请输入你想了解的部门的编号");
            Scanner sc=new Scanner(System.in);
            int command=sc.nextInt();
            if(command>alldepartment.size()||command<1)
            {
                System.out.println("输入有误，请重新输入");
                continue;
            }
            else
            {

                for (int i = 0; i < alldepartment.get(command-1).getDoctors().size(); i++)
                {
                    System.out.println(alldepartment.get(command-1).getDoctors().get(i).getName());
                }
                break;
            }
        }
    }

9，查询医生的全部信息

public void showdoctorinfo()
    {
        for (int i = 0; i < alldoctor.size(); i++)
        {
            System.out.println(alldoctor.get(i).getName());
            System.out.println(alldoctor.get(i).getSex());
            System.out.println(alldoctor.get(i).getAge());
            System.out.println(alldoctor.get(i).getDegree());
            System.out.println(alldoctor.get(i).getAdvantage());
            System.out.println(alldoctor.get(i).getJointime());
            System.out.println(alldoctor.get(i).getId());
            System.out.println(alldoctor.get(i).getDepartment());
            System.out.println("---------------------------------------");
        }
    }

10，查找需要的医生

public doctor printfalldoctor (){
        for(int i=0;i<alldoctor.size();i++)
        {
            System.out.println((i+1)+alldoctor.get(i).getName());
        }

        doctor d;
        while(true)
        {

            }
        }
    }

13，遇到问题字符串与时间对象的格式转换

如果你遇到 LocalTime.parse() 方法无法解析时间字符串的问题，通常有以下几个原因：
格式不匹配：
输入的时间字符串格式与 LocalTime.parse() 默认的格式（HH:mm:ss）不匹配。
解决方法：使用 DateTimeFormatter 指定正确的格式。
无效的时间值：
输入的时间字符串包含无效的时间值，例如小时数超过23，分钟数或秒数超过59。
解决方法：确保输入的时间字符串是有效的。
字符集问题：
输入的时间字符串包含非数字字符或特殊字符。
解决方法：检查并清理输入字符串，确保只有有效的时间字符。
时区问题：
如果时间字符串包含时区信息，而 LocalTime 不支持时区。
解决方法：使用 ZonedDateTime 或 OffsetTime 来处理带时区的时间字符串。

LocalDate.parse() 方法默认使用 ISO_LOCAL_DATE 格式，即 yyyy-MM-dd。如果你的输入时间字符串格式与此默认格式不匹配，你需要使用 DateTimeFormatter 来指定正确的格式。

14，病人预约

14.1预约成功后打印信息

public oppintment bookingsc(oppintment o,doctor d)
    {
        System.out.println("请输入您的姓名");
        Scanner sc=new Scanner(System.in);
        String name=sc.next();
        o.setName(name);
        System.out.println("请输入您的性别");
        String sex=sc.next();
        o.setSex(sex);
        System.out.println("请输入您的年龄");
        int age=sc.nextInt();
        o.setAge(age);
        System.out.println("请输入您的手机号");
        String phone=sc.next();
        o.setDesc(phone);
        System.out.println("预约成功");
        System.out.println("预约科室："+d.getDepartment());
        o.setDepartmentname(d.getDepartment());
        System.out.println("预约医生："+d.getName());
        o.setDoctor(d.getName());
        System.out.println("预约号："+o.getNum()+1);

14.3代码解释

这段代码实现了医院预约系统的预约功能。具体步骤如下：
选择医生：调用 printfalldoctor 方法显示所有医生，并让用户选择一个医生。
创建预约对象：创建一个新的 oppintment 对象。
输入预约日期：用户输入预约日期，并将其转换为 LocalDate 对象。
遍历医生的排班表：检查医生的排班表，找到与用户输入日期匹配的排班记录。
选择时间段：用户选择上午、下午或晚上的时间段。
输入预约时间：用户输入具体的预约时间，并进行验证。
验证预约时间：确保预约时间在医生的工作时间内，并且预约人数未满。
完成预约：调用 bookingsc 方法完成预约，并将预约信息添加到 allpaitent 列表中。
