Course Title: Modern Programming Language Please Java Language Code Question : Design an abstract class GeometricObject. GeometricObject must ensure that its children must implement calcArea() method. Design Rectangle18-ARID-2891 and CircleM.JibranAkram Classes as children of GeometricObject class with overridden toString() method to return “Rectangle with w Width and h Height is drawn” OR “Circle with r Radius is drawn”. The attributes of Rectangle are length, width. The attribute of Circle is radius Hint: Area of circle=πr2 , Area of rectangle= width*length

Let’s build a Player Portfolio System that has abstract classes. Inheritance using Abstract: Create a new Player Abstract class. Implement getName method in this abstract class. Define other methods as abstract. Here is an example: Abstract class PlayerA {private String name;public String getNameA(){return name;}public PlayerA(String name) {this.name = name;}abstract public int getStatsA();abstract public String getSportA();} Create NFL Player and NBA Player concrete classes that will extend Player abstract class. Think of meh=thods for these two classes and implement them Develop appropriate unit tests.
Consider the following class hierarchy: class Animal { ... } class Mammal extends Animal { ... } class Cat extends Mammal { ... } Write a generic method printArray that takes an array of any type and prints each element of the array. If the element is an instance of Animal or its subclass, the method should call the toString method of the object to print its details. Otherwise, the method should simply print the element. Your method should have the following signature: public static <T> void printArray(T[] array)

solve this by arraylist in the last of the question it has been told 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…

please do both parts part 1) Implement the Solvable inheritance structure strictly according to its UML diagram.Add comments stating where data fields, constructors, toString(), and other methods are (ifany). Neither method should have an empty body unless abstract methods.Note: You should implement the Solvable interface, abstract class Problem, regular classCodingProblem, and regular class MathProblem. part 2) Write a main() method inside of the CodingProblem class, having the following:1. Generate a random integer from 0 to 100.Hint: int num = (int)(Math.random()*100);2. Create a new instance of the CodingProblem class with random input, a String “Yourlucky number is: yourInputvalue” as output, algorithm, and programmingLanguage.Apply the concept of Polymorphism (means creating the object using the Problemclass name but CodingProbem’s constructer).3. Create a new instance of the MathProblem class with random input, its square(power of 2) as an output, your algorithm, and…

Use java programming language 1.1 Create a Student Object project. Create a Student class and use the provided UML diagram to code the instance fields, constructors and methods. Note: The module mark is the average of the participation mark and the examination mark - calculate this using the calcModuleMark() method. The determineStNumber() method should compile a student number with the first 3 letters of the student's name, a '#' symbol, and a 3-digit randomly generated number (make use of a for-loop to concatenate these 3-digits). The stNumber data field should be set in the constructor by calling the determineStNumber() method. The toString() method must compile a string to display the student number, participation mark, examination mark, and module mark, formatted in table format.

Write a java program in which Animal: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, MammalNext 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…
