急求简易自动售货机（java编程）package com.test;
import java.util.Scanner;
import com.sun.java_cup.internal.internal_error;
public class Demo {
/**
* @param args
*/
public static void main(String[] args) {
Scanner s=new Scanner(System.in);
int c;
int gum=0,cho=0,pop=0,jui=0;
do{
Demo.play_bord();
c=s.nextInt();
if(c0||c6){
System.out.println("1-6 only ,input a new choice");
c=s.nextInt();
}
switch(c){
case 1:
System.out.println("here is your gum");
gum++;
break;
case 2:
System.out.println("here is your chocolate");
cho++;
break;
case 3:
System.out.println("here is your popcorn");
pop++;
break;
case 4:
System.out.println("here is your juice");
jui++;
break;
case 5:
System.out.println(gum+" gum are sold");
System.out.println(cho+" chocolate are sold");
System.out.println(pop+" popcorn are sold");
System.out.println(gum+" juice are sold");
break;
case 6:
System.out.println("system exit");
}
}while(c!=6);
}
public static void play_bord(){
System.out.println("****这是简易售货机，请按下数字选择服务*****");
System.out.println("[1]:get gum");
System.out.println("[2]:get chocolate");
System.out.println("[3]:get popcorn");
System.out.println("[4]:get juice");
System.out.println("[5]:dispaly totalsold");
System.out.println("[6]:quit");
System.out.println("***************************");
}
}
