数组简单使用b

    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        int[] series = new int[7];
        int i;
        int sum = 0;
        for (i = 0; i < series.length; i++) {
            System.out.println("请输入第" + (i + 1) + "个数字:");
            series[i] = input.nextInt();
        }
        for (int Series : series) {
            sum += Series;
        }
        System.out.println("数列中所有数字的总和是:" + sum);
        boolean flag = false;
        int choice;
        System.out.println("
请输入您所猜想的数字:");
        choice = input.nextInt();
        for (int num : series) {
            if (choice == num) {
                flag = true;
            }
        }
        if (flag == true) {
            System.out.println("恭喜，您猜对了！！！");
        } else {
            System.out.println("很遗憾，您猜错了！！！");
        }

    }
