Hey Ankit,

So the instructions tells you to change the charge method.

  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() {
    while(!isFullyCharged())
    {
        mBarsCount++;      
    }

  }
   public boolean isFullyCharged()
  {
     return mBarsCount == MAX_ENERGY_BARS;
  }
  } 
  public boolean isBatteryEmpty() 
  {
    return mBarsCount == 0;
  }

}

If you have any questions concerning the code or if you don't understand what the instruction wants you to do, feel free to ask me :)

I hope that was helpful, Patrick

I was also making the same error, you just have to change the charge method and use the isFullyCharged to check whether to increment the battery charge.

public void charge() { while(isFullyCharged()!=true) { mBarsCount++;
}
