Java Java Objects (Retired) Harnessing the Power of Objects Incrementing

Can someone please tell me what I did wrong in the charge method. I thought I did exactly what it said but it won't work

It says to increment mBarsCount using ++ and that's what I did but it doesn't work

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() {
    return mBarsCount == MAX_ENERGY_BARS;
  }

}

You see the space that you have in between your mBarsCount and the '++'. Just delete the space- it shouldn't be there. Other than that your code looks fine.
