Question

Write a game of Hangman representing the word and the letters that have been guessed as arrays .

Your program should first ask the user to enter the word to be guessed (assuming there are two or more players, and one of them is choosing the word). Then, it should display the number of letters in the word (each letter represented by an underscore "_" to indicate that the users haven't guessed it yet), the letters that have been guessed, and the number of guesses the users have left (starting with 20). An updated version of this information should be displayed after every guess. If the user guesses the word, the program should tell them that they win and terminate. If they exhaust their guesses, the program should tell them that they lose and then terminate.

Java code for hangman game.
