Cant understand the question for the increment part challenge? 

While(mBarsCount != MAX) {

mBarsCount++;

}

now wht to 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 charge() {
    mBarsCount = MAX_ENERGY_BARS;
  }

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

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

  while(mBarsCount != MAX_ENERGY_BARS){
    mBarsCount++;

  }



}

Hi Nikhil,

For this challenge you need to call the isFullyCharged method within a while loop so that your mBarsCount class property only increments until the boolean return value of isFullyCharged equals true which means the number set for mBarsCount equals that of MAX_ENERGY_BARS.

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

Hope that helps.
