java-hangman

Java implementation of hangman.

Motivation

This project can be used as an entry-point to learn about different Java Tools/Frameworks. Hangman is very simple game but has lot of room to expand the complexity of the code.

  • Hard-coded Single word -> Words per Topic in a Database
  • Single App -> Client-Server
  • CLI -> Web GUI
  • Etc

Game rules

This is one of the best known games worldwide, still, there's no harm in having the rules stated explicitly:

  • A secret word is selected
  • A blank line per letter is drawn
  • The gallow is drawn
  • Player tries to guess one letter. If exists, all occurrences of the letter are written. Otherwise another part of the man is drawn (Head, Body, one leg at a time, one arm at a time)
  • Wins if word is complete before all man is drawn (i.e. 6 misses)

DB

Makes use of postgreSQL database. DB properties should be set in db.properties file (copy from db.properties.example).

There are 3 scripts that get packed into build/libs/db.zip

  • db.sql Creates hangman database and hangman_user to access it. Should be executed as admin
  • schema.sql Creates database schema. Should be executed as hangman_user -``initDB.sql` Inserts some data so that the game is playable. Should be executed as hangman_user

And also 2 helper shell scripts

  • setupDB.sh (Re)create DB and invokes resetSchema.sh
  • resetSchema.sh (Re)create tables and inserts some initial words to be played
