I wrote a Hangman text-based game in Java that needs to include the features that I included in the comments of my code.
In short, the game will ask the user to type a word that they (or a 2nd person) will then guess. The word will be censored by the program. The program will tell the user if their guessed letter is in the word or not, and show the progress of the censored word after each guess. If the user already guessed the letter before, the program will tell the user of that and show their previous guesses without repeating any letters. The program will show the number of attempts at the end.
The code I wrote below works and has all the features I listed. But it seems not optimal and probably with very poor etiquette, as I'm self-taught thus far. Therefore, I'm looking for any advice that will make this code better and to ensure I don't get into any bad habits (I probably already have haha) as I continue to learn Java by myself.
//Simple Hangman game where user types a word, program stores it in all CAPS for easier user readability and censors the word (i.e *****)
//User then guesses one letter at a time until the entire word is guessed. Program will inform the user if the guess is in the word, and show the progress of the word after each guess.
//If the guessed letter is in the word, program will print out the # of times the letter is in the word.
//Program will store and print out # of guesses (attempts) needed to guess the word at the end of the program.
//If user tries to duplicate a previous guess, program will inform user of that and show previous guesses by user. Attempt count will not go up for duplicate guesses.
//When the program shows previous guesses by the user (using a string), it cannot contain duplicate letters. (i.e: if user guesses 's' twice, 's' will still only show up once in the string)
//StackOverFlow readers: This program works as intended, but as a self-taught beginner coder, I need assistance on optimal coding style (less lines the better) and good coding principles/etiquette
//I definitely think there are much better ways to code this, but I cannot think of any more (as you probably noticed, this is v3, which has more features and yet similar amount of lines as version 1 haha)
//All and any help is appreciated! Thank you :D
