5,799 PointsHow do i implement this
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() {
while(!charge())
{
mBarsCount++;
}
return mBarsCount == MAX_ENERGY_BARS;
}
}

try to put the while loop inside the charge method. For the while condition you should use the isFullyCharge method. The condition should say: While not fully charged increment the mBarsCount.
Let us know if you are stuck ...
