图书浏览记录类 java代码

在Java中，我们可以创建一个`BookRecord`类来表示用户的图书浏览记录。这个类可以包含一些基本属性，比如书籍ID、标题、作者以及访问时间等。以下是一个简单的类设计：

import java.util.Date;

public class BookRecord {
    private int bookId; // 书籍ID
    private String title; // 书籍标题
    private String author; // 作者名字
    private Date visitTime; // 访问时间

    // 默认构造函数
    public BookRecord() {}

    // 参数构造函数
    public BookRecord(int bookId, String title, String author, Date visitTime) {
        this.bookId = bookId;
        this.title = title;
        this.author = author;
        this.visitTime = visitTime;
    }

    // 获取和设置方法
    public int getBookId() { return bookId; }
    public void setBookId(int bookId) { this.bookId = bookId; }

    public String getTitle() { return title; }
    public void setTitle(String title) { this.title = title; }

    public String getAuthor() { return author; }
    public void setAuthor(String author) { this.author = author; }

    public Date getVisitTime() { return visitTime; }
    public void setVisitTime(Date visitTime) { this.visitTime = visitTime; }

    @Override
    public String toString() {
        return "BookRecord{" +
                "bookId=" + bookId +
                ", title='" + title + '\'' +
                ", author='" + author + '\'' +
                ", visitTime=" + visitTime +
                '}';
    }
}

// 示例用途：
BookRecord record = new BookRecord(1, "Java核心技术", "Thinking in Java", new Date());
System.out.println(record); // 输出图书浏览记录的信息
