Arrays类常用方法

public class Demo03 {      public static void main(String[] args) {          int[] nums = {5,2,86,12,45,756,12,3,1,9,32,7856};          System.out.println(Arrays.toString(nums));          //排序         Arrays.sort(nums);          System.out.println(Arrays.toString(nums));          //二分查找 PS：调用此方法前必须排序，因为二分查找是基于顺序表。         int result = Arrays.binarySearch(nums, 32);         System.out.println(result);          //打印输出         Arrays.toString(nums);          //填充         Arrays.fill(nums,0);          //复制         int[] nums2 = Arrays.copyOf(nums, 10);     } }
