判断是否在数组中，若在输入其下标，否则输入-1

编写程序，在程序中初始化一个数据，有10个元素，同时赋好值，从键盘输入一个数x，判断是否在数组中，若在输入其下标，否则输入-1

方法①

public static void main(String[] args) {
        int[] nums = new int[]{1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
        Scanner scanner = new Scanner(System.in);
        int input = scanner.nextInt();
        int result = -1;
        for (int i = 0; i < nums.length; i++) {
            if (nums[i] == input) {
                result = i;
            }
        }
        System.out.println(result);
}

public static void main(String[] args) {
        int[] nums = new int[]{1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
        Scanner scanner = new Scanner(System.in);
        int input = scanner.nextInt();
        int result = -1;
        int c = 0;
        for (int i : nums) {
            if (i == input) {
                result = c;
            }
            c++;
        }
        System.out.println(result);
    }
