8,597 PointsIs the website bugged? Why will this not go through?
I wrapped kart.drive in the try-catch and when asked to use the getMessage method I did, still not going through
class Example {
public static void main(String[] args) {
GoKart kart = new GoKart("purple");
if (kart.isBatteryEmpty()) {
System.out.println("The battery is empty");
}
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("The battery is empty");
}
lapsDriven += laps;
barCount -= laps;
}
}

24,063 Pointscode seems to work as far as the Example.java file. The only difference i can see, when the challenge does not succeed is in this line.
throw new IllegalArgumentException("The battery is empty");
In the challenge it's
throw new IllegalArgumentException("Not enough battery remains");
