使用java集合，冒泡排序法实现book类按价格进行排序

1.代码实现

package list;

import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;

public class test2 {
    public static void main(String[] args) {
        List list=new ArrayList();  
        list.add(new Book("三国",67.2));
        list.add(new Book("水浒",44.3));
        list.add(new Book("红楼梦",27.2));
        list.add(new Book("活着",23.4));
        System.out.println("排序前为：");
        for(Object o:list){
            System.out.println(o);
        }
        //冒泡排序
        bubble(list);

        System.out.println("排序后为：");
        Iterator iterator = list.iterator();
        while(iterator.hasNext()){
            System.out.println(iterator.next());
        }

    }
    //冒泡排序
    public static void bubble(List list){
        for(int i=0;i< list.size()-1;i++){
            for(int j=0;jbook2.getPrice()){   //按照升序进行排序
                    list.set(j,book2);
                    list.set(j+1,book1);
                }
            }
        }
    }
}

class Book{
    private String name;
    private double price;

    public Book(String name, double price) {
        this.name = name;
        this.price = price;
    }

    public String getName() {
        return name;
    }

    public double getPrice() {
        return price;
    }

    @Override
    public String toString() {
        return "Book{" +
                "name='" + name + ''' +
                ", price=" + price +
                '}';
    }
}
