What am I doing wrongg??
class Example {
public static void main(String[] args) {
GoKart kart = new GoKart("purple");
if (kart.isBatteryEmpty()) {
System.out.println("The battery is empty");
}
// kart.drive(42);
}
try {
kart.drive(42);
} catch (IllegalArgumentException iae) {
System.out.println(iae.getMessage());
}
}
class GoKart {
public static final int MAX_BARS = 8;
private int barCount;
private String color;
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) {
if (laps > barCount) {
throw new IllegalArgumentException("Not enough battery remains");
}
lapsDriven += laps;
barCount -= laps;
}
}

Your code logic is good, but you just have some misplaced brackets.
// kart.drive(42);
} <---- extra bracket should not be here
Balance out your brackets and you're code will pass the challenge. If you hit the Preview button, it will try and tell you what the error was. Hope that helps.
