java纯空白呀，求解答，怎么写，我不理解在帮写个注释，给个答案我自己研究研究

考虑代表 Zoom 会议参与者的给定类。

创建一个与上述 Participant 类一起使用的 Meeting 类。 除了也被视为参与者的主持人之外，会议最多可以有 25 名参与者。 它应该包含适当的属性、构造函数以及在 Participant 中调用的方法（即 addParticipant 和 getHostName）。

Zoom 还引入了限制，即所有活动会议的参与者总数最多只能为 1,000,000 人。 通过向 Meeting 类添加适当的静态属性并对 addParticipant 方法进行必要的更改来反映这一点（提示：如果添加参与者失败，该方法是否应该返回某些内容？如果是这样，应如何将 Participant 类中的 joinMeeting 更新为 考虑到这一点吗？）。

扩展：想一下是否可以在 Meeting 类中不使用静态属性的情况下添加此更改？ 为什么或者为什么不？

Participant.java

public class Participant {
    private String name;
    private boolean videoOn = false;
    private boolean muted = true;

    public Participant(String name) {
        this.name = name;
    }

    public String getName() {
        return this.name;
    }

    public void joinMeeting(Meeting workshop) {
        workshop.addParticipant(this);
        // participants would greet the meeting's host after joining:)
        this.videoOn = true;
        this.muted = false;
        System.out.println(this.name + " says hi to " + workshop.getHostName());
    }
    
}

Meeting.java

public class Meeting{
    
}

java学了一周了
我不理解怎么将Participant.java和Meeting.java联系起来，而且其中没有main怎么运行

public class Meeting {
    private static final int MAX_PARTICIPANTS = 25;
    private static final int MAX_TOTAL_PARTICIPANTS = 1000000;

    private String hostName;
    private ArrayList<Participant> participants;

    public Meeting(String hostName) {
        this.hostName = hostName;
        this.participants = new ArrayList<>();
    }
    
    public String getHostName() {
        return this.hostName;
    }

    public void addParticipant(Participant participant) {
        if (participants.size() < MAX_PARTICIPANTS && participants.size() < MAX_TOTAL_PARTICIPANTS) {
            participants.add(participant);
            System.out.println(participant.getName() + " has joined the meeting.");
        } else {
            System.out.println("Cannot add participant. The meeting is full or the total number of participants across all active meetings has reached the limit.");
        }
    }
}

答案请参见以下markdown格式:

// Participant.java
public class Participant {
    private String name;
    private boolean videoOn = false;
    private boolean muted = true;

    public Participant(String name) {
        this.name = name;
    }

    public String getName() {
        return this.name;
    }

    public void joinMeeting(Meeting meeting) {
        meeting.addParticipant(this);
        this.videoOn = true;
        this.muted = false;
        System.out.println(this.name + " says hi to " + meeting.getHostName());
    }
}

// Meeting.java
public class Meeting {
    private static final int MAX_PARTICIPANTS = 25;
    private static final int MAX_TOTAL_PARTICIPANTS = 1_000_000;

    private Participant[] participants;
    private int participantCount;
    private String hostName;

    public Meeting(String hostName) {
        this.hostName = hostName;
        this.participants = new Participant[MAX_PARTICIPANTS];
        this.participantCount = 0;
    }

    public void addParticipant(Participant participant) {
        if (participantCount < MAX_PARTICIPANTS && participantCount < MAX_TOTAL_PARTICIPANTS) {
            participants[participantCount] = participant;
            participantCount++;
        } else {
            // Return or handle failure to add participant
            // For example, you can throw an exception or display an error message
        }
    }

    public String getHostName() {
        return this.hostName;
    }

    public void startMeeting() {
        // TODO: Implement meeting logic
    }

    public static void main(String[] args) {
        Meeting meeting = new Meeting("Host Name");
        Participant participant1 = new Participant("Participant 1");
        Participant participant2 = new Participant("Participant 2");

        participant1.joinMeeting(meeting);
        participant2.joinMeeting(meeting);
    }
}
