编写一个 Book类java，用于描述个人藏书，包含私有化属性：作者Author 、 书名 Title 、价格 Price 、出版社 Publisher、出版年份 Published Year 五个属性。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。

好的，以下是 Book 类的 Java 代码：

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

    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;
    }

    public String getAuthor() {
        return author;
    }

    public String getTitle() {
        return title;
    }

    public double getPrice() {
        return price;
    }

    public String getPublisher() {
        return publisher;
    }

    public int getPublishedYear() {
        return publishedYear;
    }
}

以下是 BookTest 类，用于测试 Book 类：

public class BookTest {
    public static void main(String[] args) {
        Book book = new Book("J.K. Rowling", "Harry Potter and the Philosopher's Stone", 9.99, "Bloomsbury", 1997);

        System.out.println("Author: " + book.getAuthor());
        System.out.println("Title: " + book.getTitle());
        System.out.println("Price: " + book.getPrice());
        System.out.println("Publisher: " + book.getPublisher());
        System.out.println("Published Year: " + book.getPublishedYear());
    }
}

当你运行 BookTest 类时，会输出以下内容：

Author: J.K. Rowling
Title: Harry Potter and the Philosopher's Stone
Price: 9.99
Publisher: Bloomsbury
Published Year: 1997
