629 PointsHalp! I can't seem to solve this!
I'm sure i'm close but I don't get this: Okay, so let's throw an IllegalArgumentException from the drive method if the requested number of laps cannot be completed on the current battery level. Make the exception message "Not enough battery remains".
public class GoKart {
public static final int MAX_BARS = 8;
private String mColor;
private int mBarsCount;
public GoKart(String color) {
mColor = color;
mBarsCount = 0;
}
public String getColor() {
return mColor;
}
public void drive() {
drive(1);
}
public void drive(int laps) {
// Other driving code omitted for clarity purposes
mBarsCount -= laps;
try{
mBarsCount < laps;
System.out.println("This will never happen");
} catch(IllegalArgumentException iae) {
System.out.println("Not enough battery remains");
System.out.printf("The error was: %s\n", iae.getMessage());
}
}
public void charge() {
while (!isFullyCharged()) {
mBarsCount++;
}
}
public boolean isBatteryEmpty() {
return mBarsCount == 0;
}
public boolean isFullyCharged() {
return mBarsCount == MAX_BARS;
}
}

Java Web Development Techdegree Graduate 22,175 PointsMake sure you check community answers before you, by clicking on "Throwing Exception" above the title of your question at the top of the page:
Java -> Java Objects -> Harnessing the Power of Objects -> Throwing Exceptions
That will lead you to community answers, asked about this challenge.
Here is direct link, just in case:
https://teamtreehouse.com/community/code-challenge:5912
There you will find a lot of helpful ones.
Check this one for example
https://teamtreehouse.com/community/exceptions-getting-an-error
It has a nice hint how to proceed.
About your code, I can just say one thing:
You have to THROW exception, and not CATCH it with try ...catch
block ...
