java日历行程提醒

以下是一个使用Java实现日历行程提醒的示例：

import java.util.ArrayList;import java.util.Calendar;
import java.util.List;
import java.util.Scanner;

class Event {
    private String title;
    private Calendar date;

    public Event(String title, Calendar date) {
        this.title = title;
        this.date = date;
    }

    public String getTitle() {
        return title;
    }

    public Calendar getDate() {
        return date;
    }
}

class CalendarReminder {
    private List<Event> events;

    public CalendarReminder() {
        events = new ArrayList<>();
    }

    public void addEvent(String title, Calendar date) {
        Event event = new Event(title, date);
        events.add(event);
    }

    public void deleteEvent(Calendar date) {
        for (Event event : events) {
            if (event.getDate().equals(date)) {
                events.remove(event);
                break;
            }
        }
    }

    public void editEvent(Calendar date, String newTitle) {
        for (Event event : events) {
            if (event.getDate().equals(date)) {
                event.setTitle(newTitle);
                break;
            }
        }
    }

        for (Event event : events) {

                System.out.println(event.getTitle());
            }
        }
    }
