public boolean isFullyCharged(){while(!isFullyCharged){mBarCount++;} return isFullyCharged();

the compiler is giving an error. what I'm making wrong with this part of the program thk guys

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() {
  // charge == false;
    while( !isFullyCharged()){ mBarsCount++;}   return isFullyCharged();
  }

Okay so there is a few errors. This part of the challenge has you change the charge() method by using the isFullyCharged() method.

The isFullyCharged() method should look like this.. it returns false unless the current barCount is equal to the max.

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

Where you need to make changes is in your charge() method, pretty much the while loop that you had in isFullyCharged.

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

So basically now instead of charge() automatically setting the battery to the max when it isn't already full it increments by one, each time checking isFullyCharged(). Once the battery is charged isFullyCharged() returns true and the while loop finishes.
