2,951 PointsHandling Exceptions: Make sure you print out the error message to the console using the exception's getMessage method.
For the life of me I can't find what is the problem to cause this, can someone tell me what's wrong with my code?
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("Whoa there cow boy, too many laps!");
System.out.printf("The error was %S", 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 left");
}
lapsDriven += laps;
barCount -= laps;
}
}

2,951 PointsResetting it did the trick. I spent 2 hours pouring through documentation to see what I did wrong but it was a bug in the exercise....

803 PointsSystem.out.printf("The error was %S", iae.getMessage());
For that line you wrote, you need a lowercase %s. You wrote it with a capital. If that doesn't work, try deleting the .getMessage() idk where this came from
This should work: System.out.printf("The error was %s", iae);

2,951 PointsI changed the s to lower case but it still won't accept the answer, when I run the preview, the code works perfectly. I'm truly at a loss here

When I implement jason yu's corrections he provided for you, the challenge does pass. So the code is correct. Resetting the challenge should help. :)
