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
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;
}
while (mBarsCount < MAX_ENERGY_BARS) {
System.out.printf("Energy BARS", mBarsCount);
if !(mBarsCount == MAX_ENERGY_BARS)
{
mBarsCount++;
}
}
}

Please be careful with the { } placements
You have
public boolean isFullyCharged() { return mBarsCount == MAX_ENERGY_BARS; }
while (mBarsCount < MAX_ENERGY_BARS) { System.out.printf("Energy BARS", mBarsCount); if !(mBarsCount == MAX_ENERGY_BARS) { mBarsCount++; } }
I believe it should be (not tested)
public boolean isFullyCharged() {
while (mBarsCount < MAX_ENERGY_BARS) {
mBarsCount++;
System.out.printf("Energy BARS", mBarsCount);
}
return mBarsCount;
}
if this answers your question, please mark the question as answered.
Thanks

934 Pointsit didn't work for me but here is my version according to what they taught me on the video.
public boolean isFullyCharged() { boolean isFullyCharged = true; while( mBarsCount != MAX_ENERGY_BARS) { isFullyCharged = false; mBarsCount++; System.out.println(" Batter is fully charged!"); } return isFullyCharged; }
