2.编写一个Book类，用于描述个人藏书，包含作者 Author、书名 Title、价格Price、出版社 Publisher、出版年份Published Year 共5个属性。然后编写一个测试类 BookTest，对Book类进行测试，输出正确的属性值。

首先，我们来创建一个名为`Book`的类，它将包含描述书籍的基本属性：

public class Book {
    private String author;
    private String title;
    private double price;
    private String publisher;
    private int publishedYear;

    // 构造方法，用于设置初始值
    public Book(String author, String title, double price, String publisher, int publishedYear) {
        this.author = author;
        this.title = title;
        this.price = price;
        this.publisher = publisher;
        this.publishedYear = publishedYear;
    }

    // getter和setter方法
    public String getAuthor() {
        return author;
    }

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

    public String getTitle() {
        return title;
    }

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

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }

    public String getPublisher() {
        return publisher;
    }

    public void setPublisher(String publisher) {
        this.publisher = publisher;
    }

    public int getPublishedYear() {
        return publishedYear;
    }

    public void setPublishedYear(int publishedYear) {
        this.publishedYear = publishedYear;
    }
}

// 现在创建一个测试类BookTest来验证Book类
public class BookTest {
    public static void main(String[] args) {
        // 创建一个Book对象
        Book book = new Book("J.K.罗琳", "哈利·波特与魔法石", 200, " Bloomsbury Publishing", 1997);

        // 输出属性值
        System.out.println("作者: " + book.getAuthor());
        System.out.println("书名: " + book.getTitle());
        System.out.println("价格: " + book.getPrice());
        System.out.println("出版社: " + book.getPublisher());
        System.out.println("出版年份: " + book.getPublishedYear());

        // 测试用完后记得清理资源或关闭连接等
    }
}

在这个测试类中，我们创建了一个`Book`对象，并通过getter方法获取并打印每个属性的值。
