Courses Plus Student 5,457 PointsHelp with Bummer: Make sure you throw the exception before you change the barCount and lapsDriven fields.
Am I updating the variables barCount and lapsDriven in the wrong location? It is after the exception.
class GoKart {
public static final int MAX_BARS = 8;
private String color;
private int barCount;
private int lapsDriven;
public GoKart(String color) {
this.color = color;
}
public String getColor() {
return color;
}
public void charge() {
barCount = MAX_BARS;
}
public boolean isBatteryEmpty() {
return barCount == 0;
}
public boolean isFullyCharged() {
return MAX_BARS == barCount;
}
public void drive() {
drive(1);
}
public void drive(int laps) {
int newAmount = barCount -= laps;
if (newAmount < 0) {
throw new IllegalArgumentException("Not Enough Bars!");
}
barCount = newAmount;
lapsDriven += laps;
}
}

For the benefit of other readers, the "barcount" was being updated with a subtracting assignment ("-=") in the calculation instead of a simple subtraction ("-").
