Reverse guessing game (java)

I am supposed to be doing a reverse guessing game where the user picks a number and the computer guesses but I am having a hard time getting the computer to not repeat what it has already guessed. But this is what I have done so far:

public static void main(String[] args)
{ 
    Scanner console = new Scanner(System.in);
    intro();
    game (console);

}

/*
 * This method just prints out the intro before the game.
 */

public static void intro ()
{
    System.out.println("This program has you, the user, choose a number");
    System.out.println("between 1 and 10, then I, the computer, will try");
    System.out.println("my best to guess it.");
    System.out.println();
}
 /*
  * This method is the game part that is going to ask the user to choose a number (1-10)
  */
public static boolean  game (Scanner console)
{
    String user;
    int min= 1;
    int max = 10;
    int computer;
    int numberOfGuesses = 0;
    boolean again = false; 
    Random rand = new Random();
    System.out.println("User, what is your number? ");
    int usernumber = console.nextInt();

    while (!again)
    {
        if (min==max)
        {
            computer= min;
        }
        else
        {
            computer = Math.abs (rand.nextInt()) % (max - min) + min;
        }

        System.out.print("Is it " + computer + "? (y/n) ");
         user = console.next();


        if (user.charAt(0) == 'y')
        {
            numberOfGuesses++;
            System.out.println("I go your number of " + usernumber + " correct in " + numberOfGuesses + " guess(es).");
            again = true;
            return again;
        }

        if (user.charAt(0) == 'n')
        {


            if(min >=computer)
            {
                min = computer +1; 
            }
            else
            {
                max = computer -1 ;
            }
            numberOfGuesses++;
            again = false;
        }

    }


    return again;
}
