List小练习，实现添加图书，并且有序遍历

 @SuppressWarnings({"all"})public static void main(String[] args) {List list = new LinkedList();
//        List list = new Vector();
//        List list = new ArrayList();list.add(new Book1("红楼小梦",35.5,"曹雪芹"));list.add(new Book1("霸王别姬",98.5,"张艺谋"));list.add(new Book1("一代妖姬",30.5,"未知"));list.add(new Book1("前任三传",32.5,"郑恺"));for (Object o :list) {System.out.println(o);}Bubble(list);System.out.println("=========排序后:========");for (Object o :list) {System.out.println(o);}}//冒泡排序public static void Bubble(List list){for (int i = 0; i < list.size()-1; i++){for (int j = 0; j < list.size()-i-1; j++) {Book1 book1 = (Book1) list.get(j);Book1 book2 = (Book1) list.get(j+1);if(book1.getPrice()> book2.getPrice()){list.set(j,book2);list.set(j+1,book1);}}}}
}
class Book1{private String name;private double price;private String author;@Overridepublic String toString() {return "名称:" +name +"\t\t价格:" + price +"\t\t作者:" + author;}public String getName() {return name;}public void setName(String name) {this.name = name;}public double getPrice() {return price;}public void setPrice(double price) {this.price = price;}public String getAuthor() {return author;}public void setAuthor(String author) {this.author = author;}public Book1(String name, double price, String author) {this.name = name;this.price = price;this.author = author;}

传送门：为什么这里不需要中间变量就可以直接使用冒泡排序？ 

为什么不懂wb​​​​​​​list.set交换数据需要（or不需要）添加其他中间变量，两个例子告诉你-CSDN博客
