So create that while loop inside the charged method code block taking the isFullyCharged method with the NOT (!) operator in front. Increment mBarsCount and then increment mBarsCount inside the loop with ++. This is stating that while the battery is not fully charged we are going to keep on charging it. Hope this helps. Good coding to ya!

 public void charge() {
    while(!isFullyCharged()){
    mBarsCount++;
    }
  }

I am not an instructor and probably not the best person to ask.
