You are required to implement a Java application that allows a user to create, read, update and delete data in a table in a MySQL database. Your program must use a Java class that encapsulates all the code to access the database (such classes are used to create ‘data access objects'). This class should be implemented using the JDBC library. Your program should present the user with a menu of choices, including the ability to create, read (or view), update and delete the entities in the database table. The code used to implement the user interface of the application should be encapsulated in a single class as much as possible. The code to implement the options available on the menu(es) should be encapsulated inside the main method (or within the other methods in the class containing the main method). This program design is known as the Model-View-Controller design pattern.
