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);
} catch(IllegalArgumentException iae) {
System.out.println(iae);
}
public void drive(int laps) {
// Other driving code omitted for clarity purposes
if (mBarsCount-laps<=0) {
throw(new IllegalArgumentException("Not enough battery remains"));
}
mBarsCount -= laps;
}
public void charge() {
while (!isFullyCharged()) {
mBarsCount++;
}
}
public boolean isBatteryEmpty() {
return mBarsCount == 0;
}
public boolean isFullyCharged() {
return mBarsCount == MAX_BARS;
}
}

Treehouse TeacherYou have the correct code in your second drive()
function, but you have unnecessary code in the first drive()
method. Leave the first one untouched from the prompting code and you should be good.
Happy coding;
