Use ++ to increment the mBarsCount member field.

I am using ++ but the challenge keeps saying Use ++ to increment the mBarsCount member field. what is wrong with the code?

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;
  }

}

Hey there Taebin,

You've pretty much got it, except there is a space where there shouldn't be. The ++ needs to be right against the variable it's incrementing. Just remove the space and you're good to go.

Keep Coding! :) :dizzy:
