跪谢！求用JAVA编写一个自动贩卖机的程序

import java.util.Scanner

public class Shop

private String coffee="咖啡做早厅"

private String coke="可乐"

private String tea="茶"

private double coffeeprice=2.00

private double cokeprice=3.00

{

}

{

if(i==1)

{

System.out.println("你选择的是咖啡")

}

if(i==2)

{

System.out.println("你纯隐选择的是可乐")

}

if(i==3)

{

System.out.println("你选择的是茶")

}

}

public double getShopping(int i,double p)

{

if(i==1)

{

if(p<coffeeprice)

{

System.out.println("您的钱不够买此商品")

}

else

{

price=p-coffeeprice

}

}

if(i==2)

}

else

{

price=p-teaprice

}

}

return price

}

public static void main(String[] args)

{

Shop shop=new Shop()

try

{

System.out.println("请选择你睁缓想要的商品\n 1.咖啡 2.可乐 3.茶")

Scanner si=new Scanner(System.in)
