challenge asks me to create a method isBatteryEmpty and execute in it whether the GoKart needs to be charged or not ?

Create a helper method that returns whether or not the GoKart needs to be charged. Make it public and name it isBatteryEmpty.

Do I have to include any statement like this "return _____;" in the isBatteryEmpty method. I meant do I have to return anything in this method ?

Thank you

GoKart.java 
public class GoKart {
  public static final int MAX_BARS = 8;
  private String mColor;
  private int mBarsCount;

  public GoKart(String color) {
    mColor = color;
    mBarsCount = 0;
  }

 public isBatteryEmpty {  //I made this method which has errors

System.out.println("Does the GoKart needs to be charged or not")  
}

  public String getColor() {
    return mColor;
  }

  public void charge() {
    mBarsCount = MAX_BARS;
  }
}

Hello Sameer,

All you need to do is determine if the battery is not charged by checking if mBarsCount id equal to MAX_BARS snd return a boolean of true or false. Therefore, make the return type of the method a boolean and just return mBarsCount == MAX_BARS;

Hope that helps.

Regards,

Chris
