Java实现会议室预约和审核的代码实现

以下是一个简单的 Java 代码实现会议室预约和审核的示例：

import java.util.ArrayList;
import java.util.Date;
import java.util.List;

public class MeetingRoom {
    private String name;
    private List<Meeting> meetings;

    public MeetingRoom(String name) {
        this.name = name;
        meetings = new ArrayList<>();
    }

    public boolean reserveMeeting(Date start, Date end, String organizer) {
        for (Meeting meeting : meetings) {
            if (meeting.getStart().before(end) && meeting.getEnd().after(start)) {
                return false;
            }
        }
        meetings.add(new Meeting(start, end, organizer));
        return true;
    }

    public boolean cancelMeeting(Date start, String organizer) {
        for (Meeting meeting : meetings) {
            if (meeting.getStart().equals(start) && meeting.getOrganizer().equals(organizer)) {
                meetings.remove(meeting);
                return true;
            }
        }
        return false;
    }

    public void printMeetings() {
        for (Meeting meeting : meetings) {
            System.out.println(meeting);
        }
    }
}

class Meeting {
    private Date start;
    private Date end;
    private String organizer;

    public Meeting(Date start, Date end, String organizer) {
        this.start = start;
        this.end = end;
        this.organizer = organizer;
    }

    public Date getStart() {
        return start;
    }

    public Date getEnd() {
        return end;
    }

    public String getOrganizer() {
        return organizer;
    }

    @Override
    public String toString() {
        return "Meeting{" +
                "start=" + start +
                ", end=" + end +
                ", organizer='" + organizer + '\'' +
                '}';
    }
}

class MeetingReservationSystem {
    private List<MeetingRoom> rooms;

    public MeetingReservationSystem() {
        rooms = new ArrayList<>();
    }

    public void addRoom(MeetingRoom room) {
        rooms.add(room);
    }

    public MeetingRoom getRoom(String name) {
        for (MeetingRoom room : rooms) {
            if (room.getName().equals(name)) {
                return room;
            }
        }
        return null;
    }

    public static void main(String[] args) {
        MeetingReservationSystem system = new MeetingReservationSystem();

        MeetingRoom room1 = new MeetingRoom("Room 1");
        MeetingRoom room2 = new MeetingRoom("Room 2");

        system.addRoom(room1);
        system.addRoom(room2);

        room1.reserveMeeting(new Date(2022, 10, 1, 10, 0), new Date(2022, 10, 1, 11, 0), "Alice");
        room1.reserveMeeting(new Date(2022, 10, 1, 11, 0), new Date(2022, 10, 1, 12, 0), "Bob");
        room2.reserveMeeting(new Date(2022, 10, 1, 14, 0), new Date(2022, 10, 1, 15, 0), "Charlie");
        room2.reserveMeeting(new Date(2022, 10, 1, 15, 0), new Date(2022, 10, 1, 16, 0), "David");

        room1.printMeetings();
        room2.printMeetings();

        room1.cancelMeeting(new Date(2022, 10, 1, 10, 0), "Alice");
        room2.cancelMeeting(new Date(2022, 10, 1, 15, 0), "Charlie");

        room1.printMeetings();
        room2.printMeetings();
    }
}

在这个示例中，会议室被表示为 `MeetingRoom` 对象，每个会议被表示为 `Meeting` 对象。`MeetingReservationSystem` 类是一个管理多个会议室的系统。

`MeetingRoom` 类实现了 `reserveMeeting` 方法来预约会议，`cancelMeeting` 方法来取消会议，以及 `printMeetings` 方法来打印当前预约情况。

在 `MeetingReservationSystem` 类的 `main` 方法中，我们创建了两个会议室，并使用 `reserveMeeting` 方法预约了几个会议。然后使用 `printMeetings` 方法打印了每个会议室的当前预约情况。最后，我们使用 `cancelMeeting` 方法取消了两个已经预约的会议，并再次打印了当前预约情况。
