4,276 PointsWhat am I doing wrong?
I have been trying to get the right answer, but everything I do seems to be wrong. Can someone please help?
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);
system.out.println("not enough battery remains");
} catch(IllegalArgumentException iea) {
system.out.println("not enough battery remains");
system.out.printf("the error was %s", iea.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;
}
}

33,586 PointsYou have two problems and both in your Example class:
- Java is case-sensitive, system should have a capital S. You use it three times in lowercase.
- Your Example class is missing a closing curly-bracket }
Note: if in the code challenge you click on Preview you will be shown some guidance on where the errors are.
