public class Shopping {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        System.out.println("请输入T恤件数：");
        int tShirtNum = input.nextInt();
        int tShirtPrice = 245;
        int tShirtTotalPrice = tShirtNum * tShirtPrice;

        System.out.println("请输入网球鞋件数：");
        int tennisShoesNum = input.nextInt();
        int tennisShoesPrice = 570;
        int tennisShoesTotalPrice = tennisShoesNum * tennisShoesPrice;

        System.out.println("请输入网球拍件数：");
        int tennisRacketNum = input.nextInt();
        int tennisRacketPrice = 320;
        int tennisRacketTotalPrice = tennisRacketNum * tennisRacketPrice;

        int totalPrice = tShirtTotalPrice + tennisShoesTotalPrice + tennisRacketTotalPrice;
        double discount = 0.8;
        double actualPrice = totalPrice * discount;

        System.out.println("购买物品\t\t单价\t个数\t金额");
        System.out.println("T恤\t\t" + tShirtPrice + "\t" + tShirtNum + "\t" + tShirtTotalPrice);
        System.out.println("网球鞋\t\t" + tennisShoesPrice + "\t" + tennisShoesNum + "\t" + tennisShoesTotalPrice);
        System.out.println("网球拍\t\t" + tennisRacketPrice + "\t" + tennisRacketNum + "\t" + tennisRacketTotalPrice);
        System.out.println("折扣：\t\t8折");
        System.out.println("消费总金额：\t" + actualPrice);
        System.out.println("实际交费：\t");
        double payment = input.nextDouble();
        double change = payment - actualPrice;
        System.out.println("找钱：\t\t" + change);
    }
}
