java编写一个book类

以下是一个简单的 Book 类的 Java 编写示例：

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

    public Book(String title, String author, int publicationYear, String publisher, double price) {
        this.title = title;
        this.author = author;
        this.publicationYear = publicationYear;
        this.publisher = publisher;
        this.price = price;
    }

    public String getTitle() {
        return title;
    }

    public String getAuthor() {
        return author;
    }

    public int getPublicationYear() {
        return publicationYear;
    }

    public String getPublisher() {
        return publisher;
    }

    public double getPrice() {
        return price;
    }

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

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

    public void setPublicationYear(int publicationYear) {
        this.publicationYear = publicationYear;
    }

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

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

这个类包含了书籍的基本属性：书名、作者、出版年份、出版社和价格。并提供了相应的 getter 和 setter 方法来访问和修改这些属性。在构造函数中初始化对象的属性。
