定义一个ArrayList集合，存储一批书籍，书籍具有书名、作者、价格三个属性， 键盘录入一个书名时，显示该书籍的详细信息。
import .*;
class Book{
String name;

double price;
public Book(String name){
this.name = name;
}
public Book(String name,String author,double price){
this.name = name ;
this.author = author;
this.price = price;
}
public boolean equals(Book b){
return this.();
}
public String toString(){
return "书名: "+this.name+" 作者: "+this.author+" 零售价: "+this.price;
}
}
class Demo6{
