Can't understand the isFullyCharged their asking for....any ideas?

Hi everyone,

Stuck on this coding challenge I cant seem to get the isFullyCharged method correct. In the video he didnt demonstrate how to write an if statement in the method since he wrote it in the main method. Am I missing something?

GoKart.java 
public class GoKart {
  public static final int MAX_BARS = 8;
  private String mColor;
  private int mBarsCount;

  public GoKart(String color) {
    mColor = color;
    mBarsCount = 0;
  }

  public boolean isBatteryEmpty(){
     return mBarsCount == 0;
  }

  public boolean isFullyCharged(){

    return false;
  }

  public String getColor() {
    return mColor;
  }

  public void charge() {
    mBarsCount = MAX_BARS;
  }
}

You want to make it so that isFullyCharged returns true when mBarsCount == MAX_BARS.

You won't need an if statement, just remember that comparisons return a boolean value.
