Now create a helper method named isFullyCharged. It should return true if the GoKart is at max capacity.

Hi! Could anyone write what is the answer for this question? Sorry i didn't write my code but i have make so many efforts and now i am confused. Thanks for any help!

GoKart.java 
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 boolean isBatteryEmpty() {
    return mBarsCount == 0;
  }
  public boolean isFullyCharged() {
    boolean isFullyCharged = false ;
  while(!isFullyCharged())
  {mBarsCount++;}
    return mBarsCount == 1;

  public String getColor() {
    return mColor;
  }

  public void charge() {
    mBarsCount = MAX_BARS;
  }
}

Hi, Eleni Minadaki isFullyCharged method is actually quite simple

It should return true if the GoKart is at max capacity.

All you need to do is check whether mBarsCount equals MAX_BARS.

public boolean isFullyCharged() {
    return mBarsCount == MAX_BARS;
  }
