15,433 PointsHi, u got the basic idea but it's not what they wanted u to do.
//first u check if the requested laps is greater than the current barCount supply
if(laps > barCount) {
//if it return true then u throw a error and the program stop the execution of the code.
throw new IllegalArgumentException("Not enough energy bars!");
}
//if the statement return false then u can add laps to lapsDriven and use the barCount to make those laps.
lapsDriven += laps;
barCount -= laps;
}
