Create the following new Java classes, in the default package: $($Use these names exactly!$)$Restaurant$.$javaDish.java $-$ This will be an interfaceAppetizer.java $-$ This will be an abstract class, $1$ of $3$ types of DishMainCourse.java $-$ This will be an abstract class, $1$ of $3$ types of DishDessert.java $-$ This will be an abstract class, $1$ of $3$ types of DishSalad.java $-$ This will be a class, $1$ of $2$ types of AppetizerSoup.java $-$ This will be a class, $1$ of $2$ types of AppetizerSteak.java $-$ This will be a class, $1$ of $2$ types of MainCoursePasta.java $-$ This will be a class, $1$ of $2$ types of MainCourseCake.java $-$ This will be a class, $1$ of $2$ types of DessertIceCream.java $-$ This will be a class, $1$ of $2$ types of DessertThe relationships between these classes are as follows:A Restaurant contains $($has$-$a$)$ Dishes.There are $3$ types of $(\text{'}$is$-$a$\text{'})$ Dishes: Appetizers, Main Courses, and Desserts.Salad and Soup are types of Appetizer.Steak and Pasta are types of Main Course.Cake and IceCream are types of Dessert.Restaurant.javaThis class will represent a Restaurant object, which we will define as having:A name, represented as a String $($e$.$g$.,$ "Gusteau's"$)$A max count of dishes on the menu, represented as an int $($e$.$g$.,$ in Lab$1.$java, the count is set to $10)$Dishes$,$ stored as an array of Dish objects $($e$.$g$.,$ Dish$[])$A constructor that initializes all instance variables, and any other constructors as neededAn addDish$()$ method, which takes a Dish object as a parameter and returns nothingA toString$()$ method, which calls upon the toString$()$ method in Dish.java to return all needed information as a String $($see the output below$).$Getters and setters for all variablesDish.javaThis class will represent a Dish, defined as an interface. This interface should declare the following methods $($for the subclasses to implement$)$:A method isVegetarian$(),$ which takes no parameters and returns a boolean indicating whether or not the dish is vegetarianA getName$()$ method, which takes no parameters and returns a String of the dishs name $($e$.$g$.,$ "Caesar Salad"$)$A getType$()$ method, which takes no parameters and returns a String of the dishs type $($e$.$g$.,$ "Appetizer"$)$A toString$()$ method, which returns a String representation of the dish $($see the output below$)$Appetizer$.$java, MainCourse.java, Dessert.javaThese classes will be abstract$,$ representing the types of dishes on the menu. Each class should implement the Dish interface and have:A name, represented as a String $($e$.$g$.,$ "Lobster Bisque"$)$Whether or not the dish is vegetarian, represented as a boolean $($e$.$g$.,$ false for Steak$)$A constructor that initializes all instance variables, and any other constructors as neededA toString$()$ method, which returns a String representation of the dish by calling upon "getter" methodsA getType$()$ method, fulfilling the requirements of the super classAn abstract method getSubType$(),$ which takes no parameters and returns a sub$-$type of dish $($e$.$g$.,$ "Salad"$).$ Salad.java, Soup.java, Steak.java, Pasta.java, Cake.java, IceCream.javaThese classes will be concise, representing the specific types of dishes that can be added to the menu. Each class should extend its respective abstract class and have:A constructor that initializes all instance variables, and any other constructors as neededA getSubType$()$ method that fulfills the requirements of the super classSample Output:Welcome to Gusteau's Restaurant!$-------------*$ Appetizer: Salad named Caesar Salad $($vegetarian$)*$ Appetizer: Soup named Lobster Bisque $($not vegetarian$)*$ Main Course: Steak named Ribeye Steak $($not vegetarian$)*$ Main Course: Pasta named Fettuccine Alfredo $($vegetarian$)*$ Dessert: Cake named Chocolate Cake $($vegetarian$)*$ Dessert: Ice Cream named Vanilla Ice Cream $($vegetarian$)$
