where am i getting it wrong?

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

Hey ho,

here is the code that should work fine !

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;
  }
}

There's only one problem, charge method is already define. change it's implementation. don't make another charge method. :)

Hi Carlson,

you are soooo close ...

In this challenge you don´t need to change the isFullyCharge method at all because this method is already good to go. Use it inside the charge method to proof the charge state of your GoKart. And you have the working code already:) but in the wrong method.

take this:

while(!isFullyCharged()) {
    mBarsCount ++;
    }

and paste it intoo the existing charge method. And it should be great :)

So Inside your charge method :

public void charge() {
    while (!isFullyCharged()) { 
// while not fully charged please increment the mBarsCount
//
      mBarsCount++;
    }
  }

You can delete "mBarsCount = MAX_ENERGY_BARS" inside charge() because you set the mBarsCount if your GoKart is not FullyCharged :)

Let us know if you need more help and don´t give up

What Grigorij wrote worked for me. Just refresh your page, and change the default charge method to what he wrote.

Hi Carlson,

glad to help you :)

Mark it as best answer, so other Java-Warriors can use it for their research
