Need help solving this one.

Okay, so let's use our new isFullyCharged helper method to change our implementation details of the charge method. Let's make it so it will only charge until the battery reports being fully charged.

Let's use the ! symbol and a while loop. Inside the loop increment mBarsCount.

I really dont now what to do... Have tried a lot of things but nome 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() {
    mBarsCount = MAX_ENERGY_BARS;
  }

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

  public boolean isFullyCharged() {
    return mBarsCount == MAX_ENERGY_BARS;
  }

}

Hi Victor,

you can use the charge method to proof whether the isFullyCharged() is true or false. So you can go with this:

 public void charge() {
      while(!isFullyCharged()){ //while the GoKart isn´t fully charged
            mBarsCount++;   //increment the mBarsCount
       } //so your while loop is proofing whether mBarsCount is = MAX_ENERGY_BARS and incrementing the count until it is fully charged 
  }

I hope it helps, if not let us know :)
