Java Video类使用实例

下面是一个使用Java的Video类的实例：

import java.util.Date;public class Video {    private String title;    private String description;    private String url;    private Date uploadDate;        public Video(String title, String description, String url, Date uploadDate) {        this.title = title;        this.description = description;        this.url = url;        this.uploadDate = uploadDate;    }        public String getTitle() {        return title;    }        public String getDescription() {        return description;    }        public String getUrl() {        return url;    }        public Date getUploadDate() {        return uploadDate;    }        public void setTitle(String title) {        this.title = title;    }        public void setDescription(String description) {        this.description = description;    }        public void setUrl(String url) {        this.url = url;    }        public void setUploadDate(Date uploadDate) {        this.uploadDate = uploadDate;    }        public static void main(String[] args) {        Video video = new Video("Java Tutorial", "A tutorial on Java programming language", "https://www.youtube.com/watch?v=Hl-zzrqQoSE", new Date());                System.out.println("Title: " + video.getTitle());        System.out.println("Description: " + video.getDescription());        System.out.println("URL: " + video.getUrl());        System.out.println("Upload Date: " + video.getUploadDate());                video.setTitle("Java Video Tutorial");                System.out.println("New Title: " + video.getTitle());    }}

这个例子创建了一个Video类，它有一个标题、一个描述、一个URL和一个上传日期。我们使用构造函数来创建一个Video对象，并使用getter和setter方法来访问和修改对象的属性。在主方法中，我们创建了一个Video对象并打印出它的属性。然后，我们使用setter方法修改标题，并再次打印出新的标题。
