I am lost and require assistance

If anyone can help walk me through this example i would highly appreciate it! The task is : 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.

Thank you!

GoKart.java 
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 (!isBatteryEmpty()) {
    mBarsCount ++;
   isFullyCharged = false;   
  }
    return mBarsCount == MAX_ENERGY_BARS;
  }


}

Hi Sohaib,

You're on the right track but have put your code in the wrong method, instead of putting it within isFullyCharged it should be inside charge as that's where our static code is.

See the below.

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

Happy coding!

Oh i see my mistake now, thank you for your help! This may be a dumb question on my end but i am having trouble understanding the crucial role the static code plays, if you can help I would highly appreciate it! Happy coding!

I'm no sure what you mean by static code plays, could you please elaborate.
