6,198 PointsI'm stuck....
I am confused, I understand the purpose of the videos to explain the concepts, but then I got attempt a challenge, but I find myself 9/10 times struggling to begin with because the content isn't the same. That throws me off.
When I try to just grasp the main concepts and apply those to the coding example. It works obviously when I understand it, but it seems that when I implement the same code it doesn't seem to work the same. For example in this current challenge I was using the similar code as provided in the video, tweaking it of course for the variable names.
However, I find I have tons of errors. I am just baffled, and need a little help please.
I understand the concepts, I guess I am having a rough time understanding how to write it all out, and where to put it.
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;
}
}

40,533 PointsThis challenge can be difficult to follow since the modifications to the charge method won't actually change any behavior. It's more to illustrate the use of the ++
operator and to put to use the isFullyCharged method.
So in the charge method you'll be restructuring it in the following way:
public void charge() {
// While the GoKart isn't fully charged:
// increment mBarsCount
}
