Write an interactive program that plays a game of hangman St

Write an interactive program that plays a game of hangman. Store the word to be guessed in successive elements of an array of individual characters called word. The player must guess the letters belonging to word. The program should terminate when either all letters have been guessed correctly (the player wins) or a specified number of incorrect guesses have been made (the computer wins).

Solution

Answer:

import java.util.*;
   import java.io.*;
