怎么从大到小排列？

Answer 1

package com.gnnu2016; import java.util.Arrays; import java.util.Scanner; public class HelloWorld {   public static void main(String[] args) {   int score[]={1,5,6,7,8,3,4,2,9};//定义整形数组score，有9个元素下标0-8   Arrays.sort(score);//调用sort()方法，实现数组的升序排序   for(int i=score.length-1;i>=0;i--){//for循环逆序打印输出   System.out.print(" "+score[i]);//scores.length是当前scores数组的元素个数，之所以-1是因为下标从0开始   } } }

Answer 2

简单的说sort方法还有一个倒序的参数,你添加上就支持倒序了

Answer 3

for(i=score.length-1;i>=0;i--)

Answer 4

从后往前遍历不就行了
