[Solved] Syntax error in calling a method java (newbie) [closed]

by


you can call a void method like any other method, except that you don’t have to do anything with the return value because there isn’t one.

case 2:
    listBasket(basket);
    break;

for your third case, you have to pass in both a double and an ArrayList if you want to pass 0 as your double, than you can just post a double literal.

case 3:
    /* if you don't want totalCost to go out of scope right away, 
     * declare it above the switch statement */
    double totalCost = CalcTotalCost(0.0, basket);
    ...
    break;
