I don't know what I'm doing wrong (isFullyCharged)

I thought I was getting close when it told me I forgot the ! but after I added that it just told me to try again in the error message.

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 (!isFullyCharged()) {
    mBarsCount++;}
    return mBarsCount == MAX_ENERGY_BARS;
  }

}

The code you have written is actually correct but you have placed it in the wrong method, the task is asking you to change how the charge method is implemented, not the isFullyCharged method.

In fact by placing that while loop inside the isFullyCharged method you have created an infinite recursive loop, since the loop will call isFullyCharged which will run the loop calling isFullyCharged which will run the loop again and so on and so on.

Take the while loop and put it into the charge method instead (removing the code that is already there) and you will solve the challenge.
