What am I suppose to do in the question? How would you get started?
public class GoKart {
public static final int MAX_ENERGY_BARS = 8;
private String mColor;
private int mBarsCount;
public GoKart(String color) {
mColor = color;
mBarsCount = 0;
}
public String getColor() {
return mColor;
}
public void charge() {
mBarsCount = MAX_ENERGY_BARS;
}
public boolean isBatteryEmpty() {
return mBarsCount == 0;
}
public boolean isFullyCharged() {
return mBarsCount == MAX_ENERGY_BARS;
}
}

3,065 PointsI forgot to write the question, sorry. Here it is: "Okay, so let's use our new isFullyCharged helper method to change our implementation details of the charge method. Let's make it so it will only charge until the battery reports being fully charged. Let's use the ! symbol and a while loop. Inside the loop increment mBarsCount."

Next use a while loop to add one to mBarsCount while mBarsCount is not equal to MAX_ENERGY_BARS. It wants you to use the new incrementer trick it showed you on mBarsCount, so it would look like mBarsCount++. I hope that helps you.

Treehouse Guest TeacherHello Allen,
The challenge is asking you to make the charge method continually loop until the GoKart is fully charged. To do this, you'll need to use a while loop and the isFullyCharged method to determine when to stop charging.
Each time the while loop executes, we want to add one to the mBarsCount. When the call to isFullyCharged returns true, then we'll exit the loop and return from the function.
public void charge() {
while (!isFullyCharged()) {
mBarsCount++;
}
}
I hope this helps

7,605 PointsWhat is the question? What is it asking you to do? I can't load the challenge to see what it wants you to do.
