791 PointsI don't understand my problem here
What am i doing wrong?
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(100);
System.out.println("this will not happen");
}catch (IllegalArgumentException iae){
System.out.println("Whoaa there");
System.out.println("the error was ");
}
}
}
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;
}
}

13,969 PointsMaybe you should add the exception variable?
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(100);
System.out.println("this will not happen");
}catch (IllegalArgumentException iae){
System.out.println("Whoaa there");
System.out.println("the error was " + iae);
}
} }

791 PointsThank you Geocarlos Alves but it is still not working....

7,481 PointsOK, so this one is a bit funky, but listen. There are two things you need to do. The first one: change kart.drive(100) to kart.drive(42). That was the exercise's initial state, apparently very fond of the number 42 for some reason. The second thing: on System.out.println("the error was "); add iae.getMessage().
Good luck, Shirit!

791 PointsThank you Anders. Finally the problem was the println.It should be printf. Thanks a lot.
