11,685 PointsYou're close, but there are a few things wrong.
First, the IllegalArgumentException needs to occur before the mBarsCount are -= from the laps, incase someone sets the laps above the battery level.
Second, you don't need to create a new variable, all you need is the laps and mBarsCount.
Third, you are missing curly braces in code. one { and two }}.
The code below will complete the challenge. Read through it and I hope it makes sense! :)
public void drive(int laps) {
// Other driving code omitted for clarity purposes
if (mBarsCount < laps) {
throw new IllegalArgumentException("Not enough battery remains");
}
mBarsCount -= laps;
}
