File wouldnt compile

[Jose Kampilan]

Hi.

I'm currently having a problem with compiling an exercise from Head First: Java. I think all needed classes for the game to run have been compiled except for the main method.

Here's the main method (just copied it directly from the book):

public static void main(String[] args)
{
  int numOfGuesses = 0;
  GameHelper helper = new GameHelper();
  SimpleDotCom theDotCom = new SimpleDotCom();
  int randomNum = (int) (Math.random() * 5);
  int[] locations = {randomNum, randomNum+1, randomNum+2};
  theDotCom.setLocationCells(locations);
  boolean isAlive = true;

  while(isAlive == true)
  {
    String guess = helper.getUserInput("enter a number");
    String result = theDotCom.checkYourself(guess);
    numOfGuesses++;
    if (result.equals("kill"))
    {
      isAlive = false;
      System.out.println("You took " + numOfGuesses + " guesses");

    }
  }
}

And here's the error message from the compiler:



Not sure what i did wrong here.

Is main() enclosed in a class ?

(Sorry. still new with Java.)

Huzzah. It worked.

Thanks Carey Brown.
