    Default Need help with an output problem , java hangman

    Hey guys I made a simple game where of hangman but I am running into an issue where an output of a sentence is inputted more than 2 if the word contains the same character. This is how the output looks like, I just want it to output the sentence once.

    Output :
    Correct letter, good job!

    Correct letter, good job!

    Default Re: Need help with an output problem , java hangman

    The code doesn't compile for testing because of a missing class: character

    Also please copy and paste the full contents of the console window from the test showing all the input and output for the program.

    What variable has a value that tells you if the message has been printed yet?
    If you don't understand my answer, don't ignore it, ask a question.
