Java - Guess the Secret Word
Here you can find the complete source code for guessing the secret word in Java Programming Language.
The program will read the words from the given input file and will pick up a word and store it as a secret word. It starts with displaying the number characters as "*" and the following sequence is self explanatory.
Your secret word is: **********
