Where is the variable: scan defined? The compile can not find it.

There is a variable: input that points to a Scanner object. Is that it?

Hi

thanks for replying.

I have been trying to, well basically too understand what you said there.
And i guess i need to define scan or point input to answer?
Don't really sure how to do either at the moment tho..

If you got another bone to throw out here it would probably be great.

[JamesCherrill]

You define: Scanner input = new Scanner(System.in);
You use this to read input from the user: guess = input.nextInt();
But then for the next input you have: answer = scan.next();
It looks like you have forgotten that the scanner is called "input" and have mistakenly typed (or copied?) the name "scan" instead, which is wrong.

if (answer.equalsIgnoreCase("Y"));

I'm pretty sure you DON'T have a semicolon at the end of the line there. Because of the semicolon, it skips the rest of the IF STATEMENT

else if (answer.equalsIgnoreCase("N"))
                playAgain = false;
                else 
                    okinput = false;
            }

Remove the semicolon
