Simple Java method to detect previous responses

Ok so I need to make a program in java that is basically a random number generator and the player needs to guess what number was generated, from 1-10.

I already got the code and everything works perfectly fine (Code is posted below) but I want to make it so that the user cannot use the same number twice.

Like say for instance the player enters 2 then 3 then 2 again. I want it to return "You have already entered this number" For the life of me I could not get this to work.

I've been trying with HashSets because I'm fairly certain that that method is the correct method to do it but I get tricked up when it comes to recalling the numbers that are already in the HashSet and if they are in the HashSet already then return "You have already entered this number".

I tried tinkering with

if (hs.contains(guess)) == true) 
System.out.println("You have already entered this number")

and I also put hs.add(guess) and guess being what number the player has entered. I'm really stumped and if you guys could guide me in the right direction I'd greatly appreciate it.

package guessgame;

import java.util.HashSet;
import java.util.Scanner;

public class GuessGame {

    public static void main(String[] args) {

        HashSet<Integer>hs = new HashSet();
        int GuessLogic;
        GuessLogic = (int) (Math.random() * 10 + 1);
        Scanner keyboard = new Scanner (System.in);
        int guess;
        int NumGuess;
        NumGuess = 1;

        do {
            System.out.print("Enter a guess: ");
            guess = keyboard.nextInt();
            System.out.println("Your guess is " + guess);
            if (guess == GuessLogic)
                System.out.println("You got it right!! Congrats!! Total Number of Guesses: " + NumGuess++);
            else if (guess < GuessLogic && guess > 0)
                System.out.println("You are wrong!!! Hint: Guess Higher, Guess number: " + NumGuess++);
            else if (guess > GuessLogic && guess <= 10)
                System.out.println("You are wrong!!! Hint: Guess Lower, Guess number: " + NumGuess++); 
            else
                System.out.println("Your guess is out of the specified range. Please try again." ); 
        } while (guess != GuessLogic);

    }   

} 

Here is the full version (rewritten a little).

You may want to move around NumGuess++ to wherever you want to increment the number of guesses. It seemed appropriate to put it immediately after a guess, but you may not want to increment if the Set already contains the number.

Also, moving out the range check makes the code a little cleaner.

public static void main(String[] args) {

    Scanner keyboard = new Scanner(System.in);

    HashSet<Integer> hs = new HashSet<>();
    int GuessLogic = (int) (Math.random() * 10 + 1);

    int guess;
    int NumGuess = 0;
    do {
        System.out.print("Enter a guess: ");
        guess = keyboard.nextInt();
        NumGuess++;

        if (hs.contains(guess)) {
            System.out.println("You have already entered this number");
            continue; // this will repeat the loop
        }

        if (guess < 0 || guess > 10) {
            System.out.println("Your guess is out of the specified range. Please try again.");
            continue; // this will repeat the loop
        }

        System.out.println("Your guess is " + guess);
        if (guess == GuessLogic) {
            System.out.println("You got it right!! Congrats!! Total Number of Guesses: " + NumGuess);
            return; // this will stop the method
        }
        else if (guess < GuessLogic) {
            System.out.println("You are wrong!!! Hint: Guess Higher, Guess number: " + NumGuess);
        }
        else if (guess > GuessLogic) {
            System.out.println("You are wrong!!! Hint: Guess Lower, Guess number: " + NumGuess);
        }

        hs.add(guess);

    } while (true);

}
