Array数组值升序和降序

public class Main { 4     public static void main(String[] args) { 5          6         int[] a = {9, 8, 7, 2, 3, 4, 1, 0, 6, 5}; 7         Arrays.sort(a); 8         for(int i = 0; i < a.length; i ++) { 9             System.out.print(a[i]);10         }11     }12 13 }

结果：0,1,2,3,4,5,6,7,8,9
