public void drive() {
lapsDriven++;
barCount--;
}
The drive method currently takes no parameters. (Parameters are bits of information to be used in the method.) In this case, we need to add a parameter by declaring its type and giving it a name. We will also adjust our increment/decrement shorthand to use the input param to increment/decrement our variaables. see the code below.
public void drive(int laps) { //<-- note the added parameter in the method parentheses
lapsDriven+= laps; // note we no longer use the double ++ or --, but use the += and -= and the passed in parameter
barCount-= laps;
}
