i am not able to do this task

public class Main { public static void main(String[] args) { GoKart kart = new GoKart("yellow"); if (kart.isBatteryEmpty()) { System.out.println("The battery is empty"); } try{ kart.drive(2); } catch(IllegalArgumentException e){ System.out.println("i am warning you"); } } }

Main.java 
public class Main {
    public static void main(String[] args) {
        GoKart kart = new GoKart("yellow");
        if (kart.isBatteryEmpty()) {
          System.out.println("The battery is empty");
        }
      try{
        kart.drive(2);
      }
      catch(IllegalArgumentException e){
        System.out.println("i am warning you");
      }
    }
}

Hey Neelesh,

I pasted your code and wondered why it wasn't working and that's because the code checker wants you to print out the IllegalArgumentException and nothing else.

System.out.println(e);

That's all it wants you to do. The 'e' is a variable for the illegal argument exception

Hope that cleared your question,

Kevin

Another great example as to why single letter variable names can be confusing. I tend to call my exceptions exception. :smile:
