数组简单使用a

 

 

    public static void main(String[] args) {
        double[] array = new double[5];
        Scanner input = new Scanner(System.in);
        System.out.println("请输入会员本月的消费记录:");
        for (int i = 0; i < array.length; i++) {
            System.out.print("请输入第" + (i + 1) + "笔购物金额:");
            array[i] = input.nextDouble();
        }
        System.out.println("\n序号\t\t\t金额(元)");
        double sum = 0;
        for (int j = 0; j < array.length; j++) {
            sum += array[j];
            System.out.println((j + 1) + "\t\t\t" + array[j]);
        }
        System.out.println("总金额\t\t\t" + sum);

    }
