Write a program with a word containing @ character as an input. If the word doesn't contain @, it should prompt the user for a word with @. Once a word with @ is read, it should output the word then terminate.

This is what I have done so far:

public class find {
    public static void main(String[] args) {

        System.out.println(" Please enter a word with @ ");
        Scanner scan = new Scanner(System.in);

        String bad = "@";

        String word = scan.next();
        do
            if (!word.contains(bad))
                System.out.println(" Please try again ");
            else
                System.out.println(" " + word);
        while (!word.contains(bad));
    }
}

I can get it to terminate after a word containing "@" is given as input, but if I try to add a Scanner to the line after "please try again", it says while expected.
