Vending machine program java
<p>In this vending machine code of mine, if I input excess funds it doesn't give me the change back. What am I missing here?</p>

<pre><code>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 &lt; 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 &gt;= 25){
        quarters = quarters + 1;
        change = change - 25;
    }
    while (change &gt;= 10){
        nickels = dimes + 1;
        change = change - 10;
        while (change &gt;= 5){
            nickels = nickels + 1;
            change = change - 5;
        }
    }
}
