I have no idea what's happening!

I feel so lost since this whole pez dispenser thing started!! anyone tell me what should i do!

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 do { charge() {
    mBarsCount = MAX_ENERGY_BARS;
  }
}while(!isFullyCharged) {
    mBarCount++;
  }

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

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

}

Refresh the challenge to get back to the original condition of the code. You're given a lot of methods but you only have to pay attention to isFullyCharged and charge. Moreover you only have to write code inside the body of the charge method i.e. inside the curly braces {}.

Hi Mohamed,

you need some modifications inside the charge method (not isFullyCharged()) .

The charge method should increment the mBarsCount as long the battery is not fully charged. So you can define a condition for a while loop using the isFullyCharge() method like this:

public void charge() {
   while (!isFullyCharged()) {
// while the return type of isFullyCharged() is not true
// it means while not (!) fully charged

    mBarsCount++;
// increment the mBarsCount
   }
  }

Let me know if you are still stuck.
