I don't know what I'm doing wrong.
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) {
lapsDriven += 8;
barCount -= 8;
int newlaps = lapsDriven + barCount;
if ( newlaps < MAX_BARS) {
throw new IllegalArgumentException ("Too many laps");
}}

It has been a while since I took this challenge, but I see a problem here:
public void drive(int laps) {
lapsDriven += 8;
barCount -= 8;
int newlaps = lapsDriven + barCount;
if ( newlaps < MAX_BARS) {
throw new IllegalArgumentException ("Too many laps");
}}
I suspect this should be like this:
public void drive(int laps) {
lapsDriven += laps;
barCount -= laps;
if ( barCount <= 0) {
throw new IllegalArgumentException ("Too many laps");
}}
I typed this without testing, but it should point you into the right direction.
If this answers your question, please mark question as annswered.
