需求说明：

1.已知以下三种物品的单价，要求分别输入各个物品的个数，并求出各自的总价

2.折扣为8折

3.输入消费者的实际交费，并由此算出需找零多少

package demo;
import java.util.Scanner; 
public class fukuangoumai {

	public static void main(String[] args) {
		Scanner imput = new Scanner(System.in);
		System.out.println("请输入T恤件数：");
		int a = imput.nextInt();
		int t = 245 * a;
		System.out.println("请输入网球鞋件数：");
		int b = imput.nextInt();
		int x = 570 * b;
		System.out.println("请输入网球拍件数：");
		
		int c = imput.nextInt();
		int p = 320 * c;
		int mySum = t+x+p;
		System.out.println("请输入付款金额：");
		double fukuan = imput.nextInt();
		double shiji = mySum * 0.8;
		double corn = fukuan - shiji;
		System.out.println("购买物品\t\t"+"单价\t"+"个数\t"+"金额");
		System.out.println("T恤\t\t"+"245\t"+ a+"\t" + t);
		System.out.println("网球鞋\t\t"+"570\t"+ b+"\t" + x);
		System.out.println("网球拍\t\t"+"320\t"+ c+"\t" + p);
	
		System.out.println("折扣：\t\t"+"8折");
		System.out.println("消费总金额：\t"+shiji);
		System.out.println("实际交费：\t"+fukuan);
		System.out.println("找钱：\t\t"+corn);
		
	}
