Question

Problem Description: (Game: hangman) Write a JavaFX program that lets a user play the hangman game. The user guesses a word by entering one letter at a time, as shown in Figure followings. If the user misses seven times, a hanging man swings, as shown in Figures. Once a word is finished, the user can press the Enter key to continue to guess another word. Guess a word: ***** God Missed letters Guess wordt er Missed letters. We Grawertor Mikesed letters: wps Guess wordtter To continue theme, press Figure 22.23 The program plays a hangman game. Your program will read the following words: Programming, Java, Is, Fun, (or any word that you choose) Upload: 1) Java source code 2) Screen shot for each step Without Java source code and screenshots, your homework will not be graded.
