Text-based Menu Driven Program in Java [Part 3/3]

In this video we build upon the code implemented in part 2 of the Text-based menu system series of videos by adding user input validation through the Keyboard java class. We also, replace the three arrays used to store menu data with a much more flexible ArrayList of MenuItem objects. Using an array of MenuItem objects has some knock-on effects on the displayMenu method and the conditional block code in the main menu loop, so we modify those to make the code more modular.
