私のこの自動販売機のコードでは、余分な資金を入力してもそれが私に戻ってくれません。私はここで何が欠けていますか?自動販売機プログラムjava
public static void main(String[] args) {
int Food = runMenu();
int Price = retrievePrice(Food);
int change = moneyInserted(Price);
}
public static int runMenu(){
Scanner keyboard = new Scanner(System.in);
int choice = 0 ;
System.out.println("\n\nPlease enter your selection:"
+ "\n1: Snickers \t 125"
+ "\n2: Reeses Cup \t 130"
+ "\n3: Doritoes \t 150"
+ "\n4: Pepsi \t 185"
+ "\n5: Exit ");
choice = keyboard.nextInt();
return choice;
}
public static int retrievePrice(int menuChoice){
if (menuChoice == 1)
return 125;
if (menuChoice == 2)
return 130;
if (menuChoice == 3)
return 150;
if (menuChoice == 4)
return 185;
else return 0;
}
public static int moneyInserted(int Price){
Scanner keyboard = new Scanner(System.in);
int money = 0;
System.out.println("Your item costs: " + Price + " Please enter the amount of money:");
money = keyboard.nextInt();
while (money < Price){
System.out.println("Please insert sufficient funds");
money = money + keyboard.nextInt();
}
return money - Price ;
}
public static void changeOut(int change){
int quarters = 0;
int dimes = 0;
int nickels = 0;
while (change >= 25){
quarters = quarters + 1;
change = change - 25;
}
while (change >= 10){
nickels = dimes + 1;
change = change - 10;
while (change >= 5){
nickels = nickels + 1;
change = change - 5;
}
}
}
デバッグを試しましたか? – user3707125
ここでchangeOutを呼び出していますか?私はそれを見ていないよ –
あなたのコードを正しくフォーマットすることをお勧めします。 – MikeCAT
