剛好以前寫了個 改完給你了

跪謝！求用JAVA編寫一個自動販賣機的程序

import java.util.Scanner;

public class Shop

{

private String coffee="咖啡";

private String coke="可樂";

private String tea="茶";

private double coffeeprice=2.00;

private double price=0.0;

public Shop()

{

}

public void getName(int i)

{

if(i==1)

{

System.out.println("你選擇的是咖啡");

}

if(i==2)

{

System.out.println("你選擇的是可樂");

}

if(i==3)

{

System.out.println("你選擇的是茶");

}

}

public double getShopping(int i,double p)

{

if(i==1)

{

if(pcoffeeprice)

System.out.println("您的錢不夠買此商品");

}

else

{

price=p-coffeeprice;

}

}

if(i==2)

{

if(pcokeprice)

{

System.out.println("您的錢不夠買此商品");

}

else

}

return price;

}

public static void main(String[] args)

{

Shop shop=new Shop();

try

{

System.out.println("請選擇你想要的商品\n 1.咖啡 2.可樂 3.茶");

Scanner si=new Scanner(System.in);

int i=si.nextInt();

System.out.println(" ");

if(i3||i1)

{

System.out.println("沒有此產(chǎn)品");

}

else

{

shop.getName(i);

System.out.println(" ");

System.out.print("請付賬:");

Scanner sp=new Scanner(System.in);

double p=sp.nextDouble();

System.out.println(" ");

if(shop.getShopping(i,p)!=0.0)

{

System.out.println("找你的錢："+shop.getShopping(i,p));

}

}

catch(Exception ex)
