What's wrong with my code
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 += laps;
barCount -= laps;
if (barCount ==0);
throw new IllegalArgumentExcepitions ("if there are not bars to support the laps request");
}
}

7,693 PointsA few things to make note:
- The challenge would like you to throw the exception BEFORE you change the count, meaning, you should put the if-statement at the beginning of the method.
- Make sure your if-statement is in proper syntax. Remove the semi-colon and surround your exception in curly braces to follow proper style guide presets.
- You have a spelling error in that you said
IllegalArgumentExcepitions
where is should beIllegalArgumentException
Edit: You can check your if-statement with mine, but make sure you understand before you move:
if(barCount - laps < 0) {
throw new IllegalArgumentException("Error: barCount would result in number less than zero.");
}
