五、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); } }
