Let us consider a PIZZA class which has a method that displays the message "Pizza". A PIZZA object may be decorated by 3 kinds of toppings.
 OLIVE class has a method that displays the message "With Olive".
 PEPPER class has a method that displays the message "With Pepper".
 MASHROOM class has a method that displays the message "With Mashroom".
Use the decorator pattern to create pizzas with toppings.
1) Give the UML class diagram.
2) Provide the implementation code of the UML class diagram given in question 1 in Java.
The object created by the client code should display the following message: "Pizza With Pepper With Olive With Mushroom".
