Simple Hangman game in Java

Below is a simple implementation of the Hangman game in Java. This code assumes a console-based interaction.

import java.util.Scanner;

public class HangmanGame {
    private static final String[] WORDS = {"java", "python", "hangman", "programming", "computer"};
    private static final int MAX_TRIES = 6;

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

        String secretWord = getRandomWord();
        char[] guessedLetters = new char[secretWord.length()];
        int tries = 0;

        while (true) {
            displayHangman(tries);
            displayGuessedWord(guessedLetters);

            System.out.println("Enter a letter: ");
            char guess = scanner.next().charAt(0);

            if (isLetterAlreadyGuessed(guess, guessedLetters)) {
                System.out.println("You've already guessed that letter. Try again.");
                continue;
            }

            if (secretWord.contains(String.valueOf(guess))) {
                updateGuessedLetters(secretWord, guessedLetters, guess);
            } else {
                tries++;
            }

            if (isWordGuessed(guessedLetters)) {
                System.out.println("Congratulations! You guessed the word: " + secretWord);
                break;
            }

            if (tries == MAX_TRIES) {
                displayHangman(MAX_TRIES);
                System.out.println("Sorry, you ran out of tries. The correct word was: " + secretWord);
                break;
            }
        }

        scanner.close();
    }

    private static String getRandomWord() {
        int randomIndex = (int) (Math.random() * WORDS.length);
        return WORDS[randomIndex];
    }

    private static void displayHangman(int tries) {
        // Add hangman drawing logic based on the number of tries
        // You can customize the ASCII art for the hangman as needed.
    }

    private static void displayGuessedWord(char[] guessedLetters) {
        System.out.print("Current word: ");
        for (char letter : guessedLetters) {
            if (letter == '\0') {
                System.out.print("_ ");
            } else {
                System.out.print(letter + " ");
            }
        }
        System.out.println();
    }

    private static boolean isLetterAlreadyGuessed(char guess, char[] guessedLetters) {
        for (char letter : guessedLetters) {
            if (letter == guess) {
                return true;
            }
        }
        return false;
    }

    private static void updateGuessedLetters(String secretWord, char[] guessedLetters, char guess) {
        for (int i = 0; i < secretWord.length(); i++) {
            if (secretWord.charAt(i) == guess) {
                guessedLetters[i] = guess;
            }
        }
    }

    private static boolean isWordGuessed(char[] guessedLetters) {
        for (char letter : guessedLetters) {
            if (letter == '\0') {
                return false;
            }
        }
        return true;
