编写book.java_编写一个javabean命名为:Book.java属性包括:

好的，下面是一个简单的 Book JavaBean，包括以下属性：

public class Book {
    private String title;
    private String author;
    private String publisher;
    private int yearPublished;
    private double price;
    
    // 省略 getter 和 setter 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 String getPublisher() {
        return publisher;
    }

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

    public int getYearPublished() {
        return yearPublished;
    }

    public void setYearPublished(int yearPublished) {
        this.yearPublished = yearPublished;
    }

    public double getPrice() {
        return price;
    }

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

在这个 JavaBean 中，我们定义了五个属性：title、author、publisher、yearPublished 和 price。每个属性都有对应的 getter 和 setter 方法，用于读取和设置属性的值。
