6-20 Book类的设计通常是一个关于面向对象编程中书籍模型的简单示例,它可能会包含基本的数据属性如书名(title)、作者(author)、出版年份(publishYear)和页数(pages),以及一些常见的行为方法,比如:
```java
public class Book {
// 数据成员
private String title;
private String author;
private int publishYear;
private int pages;
// 构造函数
public Book(String title, String author, int publishYear, int pages) {
this.title = title;
this.author = author;
this.publishYear = publishYear;
this.pages = pages;
}
// 获取和设置方法
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 int getPublishYear() { return publishYear; }
public void setPublishYear(int publishYear) { this.publishYear = publishYear; }
public int getPages() { return pages; }
public void setPages(int pages) { this.pages = pages; }
// 可能的方法:获取摘要、检查是否已读等
public String getSummary() { ... }
public boolean isRead() { ... } // 这里假设有一个默认值
}
```
这个设计允许创建各种具体的书籍实例,并通过标题、作者等信息区分它们。在实际应用中,可能会添加更多的特性和方法以满足需求。
