Hangman game: How to find the word?

I have to create a hangman game. I am stuck in the last step. In fact, when the user finds the word my input asks yet a letter.

Here an example: (the word to find is "non")

Enter your letter please : n

n _ n 

Enter your letter please : o

n o n 

Enter your letter please :

n o n

My problem is probably my wordFind, I don't understand how to manipulate this ?

        String[] words = {"yess", "non"};
        String wordRandom = words[(int) (Math.random() *  words.length)];
        boolean[] letterGuess = new boolean [wordRandom.length()];
        boolean wordFind = false;
        int numberAttempt = 5;

        while(numberAttempt > 0 && !wordFind){
           System.out.println("Number of attempt(s) " + numberAttempt);

           for(int i=0; i < wordRandom.length(); i++){

                if(letterGuess[i]){
                    System.out.print(wordRandom.charAt(i));
                }
                else{
                    System.out.print("- ");
                }

            }

            System.out.println(" ");

            System.out.print("Enter your letter please : ");
            char letter = input.next().charAt(0);

            int letterFound = 0;
            boolean alreadyFound = false;


            for(int i=0; i < wordRandom.length(); i++){
                if(wordRandom.charAt(i) == letter){

                    if(letterGuess[i]){
                        alreadyFound  = true;
                    }

                letterGuess[i] = true;
                letterFound++;

                }

            }
                if(alreadyFound){

                    System.out.println("Letter already proposed and it has been found ! ");

                } else{
                    if(letterFound == 1){
                        System.out.println("The letter is correct ! ");
                    }

                    else if(letterFound  > 0){
                        System.out.println("The letter is " + letterFound  + " times in the word ! ");
                    }

                    else{
                        numberAttempt--;
                        System.out.println("The letter is not in the word ! ");
                    }



            }
