Question

Can anybody help with this? I am going bizerk! This is my fourth attempt of trying to solve this java program from "Introduction to java programming" by D. Liang. This is a programming exercise from chapter 9, question 9.31. Here goes: (Game: hangman) Write a hangman game that randomly generates a word andprompts the user to guess one letter at a time. Each letter in the word is displayed as an asterisk. When the user makes a correct guess, the actual letter is then displayed. When the user finishes a word, display the number of misses and ask the user whether to continue for another word. Allow the user to enter ? to show the of incorrect guesses and the number of allowed incorrect guesses remaining. Declare an array to store words, as follows: // Use any words you like. String[] words = {"array", "write","method", ...}

Here is a sample output:

(Guess) Enter a letter in word ***** > a

(Guess) Enter a letter in word a**a* > r

(Guess) Enter a letter in word arra* > y...

Thank so very much:)
