try catch a method?

I try to create the drive method and catch it with iae but it's not correct? Can u "try" to create a method using this way?

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");
        }
        kart.drive(2);
        try {
          public void drive() {} 
        } catch (IllegalArgumentException iae) {
          System.out.printf("There was an error: %s\n", iae.getMessage());
        }
    }

}

Exceptions are caught while running a function. You're trying to create a function within try, rather than running it. You instead want to run drive(or other commands) and see if it throws exceptions. For example:

      try {
          kart.drive(2);
        } catch (IllegalArgumentException iae) {
          System.out.printf("There was an error: %s\n", iae.getMessage());
        }

 public void drive() {
  try{
  // enter commands here
  } catch (IllegalArgumentException iae) {
          System.out.printf("There was an error: %s\n", iae.getMessage());
  }
}
