Java - Guess the Secret Word Sequentially Step by Step

---

 

Here you can find the complete source code Guessing a word Sequentially in Java Programming Language. You need to guess the first character of the word first and then the second character and move on.

 

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: ********
