[Help!] What is wrong with my helper while loop?

Please Help!

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() {
     while (!isFullyCharged()) {
      mBarsCount++;
   }
  }
  public boolean isBatteryEmpty() {
    return mBarsCount == 0;
  }

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

}

There's nothing wrong with your while loop or charge method. Your isFullyCharged method is the problem. You need to delete 

boolean isFullyCharged==false;
  }

The curly bracket is an extra one that isnt needed there....this is causing a few errors. Delete that and your program should work. You also dont need that boolean declaration unless you need to method to return a default value of false.
