Hangman game in JAVA : BLUEJ

This is a simple game of Hangman created by me in java environment.

How to play ? 
In this game you are given a clue and required number of blank space for your answer. You are given a finite number of chances to fill the blanks with letters step-by-step. I have made this game different from others by making it case-sensitive, that is, "Albert" is different from "albert"
