A simple hangman game programmed in Java.

1. Add data
2. Look up data
3. Play Game
4. Exit

If the user selects the "add data" menu, the user will be asked to enter a word, validate said word for a minimum of 5 characters and a maximum of 50 characters (including spaces). The number of data is infinite (use ArrayList), and validate that there cannot be the same data (case sensitive).

If the user selects the "Look data" menu, then validate:

• If the data does not exist then display "There is no data" and ask to do the add data menu.
• If the data already exists, display the data that has been entered and sorted in ascending order (from small to large).

If the user selects the “Game” menu, then validate:

• If the data does not exist then display "There is no data" and ask to do the add data menu
• If the data already exists then:
  • i. Run random from the list of words that have been inputted
  • ii. Then display '-' the number of letters in the word that has been randomized
  • iii. Asks the user to enter a letter and checks if the letter is in the word, if there is a letter it will be displayed.

If the user selects the “exit” menu, the program will be finished.
