plz i need help with my java challenge question

Now create a helper method named isFullyCharged. It should return true if the GoKart is at max capacity.......i have tried changing some this int he method but still is not working

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() {
   if(mBarsCount.equals(MAX_BARS)){
     return true;
   }
  }


  public String getColor() {
    return mColor;
  }

  public void charge() {

Oh I just looked over your code again and then a very simple solution came to me. You've been really close and I'm sure you'll notice immediately.

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

Hi Mate,

i don't know if you need to make an if statement to check for the answer because its been a while since I made this challenge and I couldn't get bothered watching the videos again so i just made this solution and it works but I guess there are better ways to do it.

Cheers Toby.

public boolean isBatteryEmpty(){
    if (mBarsCount == 0) {
      return true;
    }
      else {
        return false;
      }
  }
    public boolean isFullyCharged(){
    if (mBarsCount == MAX_BARS) {
      return true;
    }
      else {
        return false;
      }
  }
