435 PointsNot sure what the question refers to, get stuck
I am learning the method signature and working on the drill. Not sure where my problem is.... thanks!
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(int laps) {
// Other driving code omitted for clarity purposes
mBarsCount -= laps;
}
public void drive() {
// Other driving code omitted for clarity purposes
mBarsCount+=1;
}
public void charge() {
while (!isFullyCharged()) {
mBarsCount++;
}
}
public boolean isBatteryEmpty() {
return mBarsCount == 0;
}
public boolean isFullyCharged() {
return mBarsCount == MAX_BARS;
}
}

operator instead of the +=
operator :)
public void drive() {
mBarsCount -= 1;
}
Good luck! ~alex

435 PointsThank you very much for your help! but the system gives me the following comment "Remember that you should call the existing drive method and pass in the default parameter of 1. Otherwise you would have to rewrite all that (omitted) code." not sure what does it refer to??? Thanks!!
