Java图书类

1、 设计一个图书类Book，该Book类具有属性：书籍编号（bookId），书名(bookName)，作者(author)，出版单位(publisher)，单价(price)。

a) 要求属性私有，生成其共有的get/set 方法；

b) 具有方法：show（）：该方法内显示给书籍的详细信息

c) 在创建一个Book对象的同时给该对象各属性赋初值。（带参构造）

d) 编写测试类TestBook,实现创建一个Book对象book，打印出该书的详细信息。

public class Book {
	private String bookId;
	private String bookName;
	private String author;
	private String publisher;
	private double price;
	public Book(){}
	public Book(String bookId,String bookName,String author,String publisher,double price){
		=bookId;
		=bookName;
		=author;
		=publisher;
		=price;	
	}
	public void show(){
		(bookId);
		(bookName);
		(author);
		(publisher);
		(price);
	}
	public String getBookId() {
		return bookId;
	}
	public void setBookId(String bookId) {
		 = bookId;
	}
	public String getBookName() {
		return bookName;
	}
	public void setBookName(String bookName) {
		 = bookName;
	}
	public String getAuthor() {
		return author;
	}
	public void setAuthor(String author) {
		 = author;
	}
	public String getPublisher() {
		return publisher;
	}
	public void setPublisher(String publisher) {
		 = publisher;
	}
	public double getPrice() {
		return price;
	}
	public void setPrice(double price) {
		 = price;
	}
	
}

 

public class BookTest extends Book {
	public static void main(String[] args){
		Book book=new Book("11111111","《《十万个为什么》》","不明","清华出版社",20);
		();
	}
}
