Hangman is a words guessing game for one player. The computer guesses a word and the user has to suggest letters one by one. Every time the word contains a letter, the computer opens it (all of them, if there are a few). Every time the word doesn't contain a letter, the computer gives a penalty point for the user. If there are five penalty points, the user looses. If there are no hidden letters anymore, the computer looses.
First, build it:
$ mvn clean package
Then, run:
$ java -classpath target/classes hangman.Main
This Java code is very procedural, imperative and not elegant at all.
Please, try to refactor it and improve. You're welcome to create new classes, new methods, anything. Just make sure it still builds.
When ready, please submit a pull request.
