集合的排序(正序,倒序,从大到小排序)

1.简单的集合排序

 1 package com.demo.advice;
 2 
 3 import java.util.Collections;
 4 import java.util.LinkedList;
 5 
 6 import com.alibaba.druid.sql.visitor.functions.Reverse;
 7 
 8 public class Test {
 9     public static void main(String[] args) {
10         
11         LinkedList<Integer> list = new LinkedList<Integer>();
12         list.add(1);
13         list.add(8);
14         list.add(7);
15         list.add(4);
16         list.add(5);
17         //排序前
18         System.out.println(list);
19         //倒序
20         Collections.reverse(list);
21         System.out.println(list);
22         //从大到小排序
23         Collections.sort(list);
24         System.out.println(list);
25         
26     }
27
