Java实现反转数组

反转数组

 public static void main(String[] args) {
        int[] nums = {1,2,3,4,5,5,6,7,8};  //定义数组

        //用for each 输出数组
        for (int nums1  : nums) {
            System.out.print(nums1+"  ");
        }

        int[] fan = fan(nums);            //fan方法里赋值nums,并且用名为fan的数组接收。
        out1(fan);
    }
    //反转数组操作
    public static int[] fan(int [] nums){
        int[] array = new int[nums.length];
        for (int i = 0, j = array.length-1; i < nums.length; i++,j--) {
            array[j] = nums[i];
        }
        return array;
    }
    public static void out1(int[] nums){  //输出函数
        for (int i = 0; i < nums.length ; i++) {
            System.out.print(nums[i]+"  ");
        }
    }
