Create two methods for a Hangman game in Java. The setUniqueWord() method goes through an ArrayList of input words and chooses a word at random that has not been used in the hangman game before. The guessLetter(char guess) method will take a letter that is guessed by the user and reveal it in the word if it is correct. For example, if the word that is chosen for the game is "puzzle", the user would see ******, and guess a letter. If they guessed "u", then they would see " *u**** "

The following classes have been provided:
