Task 2: abstract Class: TwoDimensionShape Create an abstract class called "TwoDimensionShape", which implement interface "Shape". See below the abstract class "TwoDimensionShape specifications: > Data Members (Attributes): All data members are privet. o uName: User name. o sName: Geometric Shape name. > Methods: o findArea(): abstract method, no implementation, it should return the area of 2D shape. o findPerimeter(): abstract method, no implementation, it should return the Perimeter of 2D shape.

Class: Square Create a class called "Square", which is inherited from“TwoDimensionShape” class. The "Square" class is used to calculate theArea and the Perimeter of square shapes when their side-length is given, or in contrast,finding the side-length of the square when the Area or the Perimeter of the square is given.The specifications of this class are below. Data Members (Attributes): All are private. sideLength: the sidelight (L) of the square. Methods/Operations/Getters/Setters: Default Constructor: when creating an object this constructor must set the side-length of the square by calling the method setSideLength(). Also, this constructor willcall the findArea() and the findPerimeter() in addition to summaryPrint() to calculateand print all needed information. User-Defined Constructor: when creating an object this constructor shouldfind the side-length of the square by calling the method findSquareSideLength()and pass the Area or the…

Create abstract class Pet , which is the abstract superclass of all animals. Declare a integer attribute called legs, which records the number of legs for this animal. Define a constructor that initializes the legs attribute. Declare an abstract method eat. Declare a concrete method walk that prints out something about how the animals walks (include the number of legs). Create the Dog class. The Dog class extends the Pet class. This class must include a String attribute to store the name and food of the pet Define a default constructor that calls the superclass constructor to specify that all dogs have 4 legs and name. override the eat and walk method. Create the Cat class that extends Pet. This class must include a String attribute to store the name of the pet, and a string to save food . Define a constructor that takes one String parameter that specifies the cat's name and food. This constructor must also call the superclass constructor to specify that all cats have four legs.…

Create a class Animal and Add a protected data member named id of integer type. Add get/set methods for id data member in Animal class with public access. Also provide default constructor this should initialize id to 0. Also provide parameterized constructor and toString method. Add an abstract method tellAboutSelf method to Animal class with public access Add another abstract method speak method to Animal class. Reptile, Bird, Mammal Next create the three child classes which extends form Animal class. Add a default constructor to each of the above created class. The constructor should initialize the id data member id, Reptile, Bird and Mammal, to 1, 2 and 3 respectively also it display a message “(class Name)’s default constructor”. E.g. for Bird it says “Bird’s default constructor”. Add a parameterized constructor to each of the above created class. The constructor should initialize the id data member, Reptile, Bird and Mammal, to the specified id passed to the constructor also it…
