Question

Write a hangman game. The program reads the words stored in a text file named hangman.txt. Words are delimited by spaces. It asks the user to guess one letter at a time, as presented in the sample run. 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 to play with another word. Declare an array to store words, as follows: // Add any words you wish in this array String[] words = {"write", "that",...};

Remember to incorporate the following in your program
1)The use of arrays (Single Dimensional Arrays or Multi-dimensional arrays).
2)The use of inheritance & polymorphism.
3)The use of exception handling.
4)The use of interfaces & abstract classes.
5)The use of Text input/output & or Binary input/output
