- 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…-Interface IResearch Scholar has two methods public void teaches (String str) and public void studies (String str). - Define classes JuniorRS and SeniorRs such that JuniorRS implements IResearchScholar and SeniorRS extends JuniorRS. - Class InterAbstrTest extends SeniorRS, and has the main method. An object of JuniorRs invokes the method studies, and an object of SeniorRS invokes methods studies and teaches.Part 1: Abstract Classes 1. Copy the source files of Circle, Rectangle and GeometricObject classes (located in LabFiles folder) and paste them in the default package (You may need to fix any problems related to package declaration). 2. Open Circle, Rectangle and GeometricObject classes using NetBeans editor and go through the classes’ implementation. 3. In the GeometricObject class add two methods called respectively getArea() and getPerimeter(). Discuss: 1. Is the area formula of a circle similar to area formula of a rectangle? Since: GeometricObject is the superclass of Circle and Rectangle, and getArea() method is a common method in both Circle and Rectangle classes. Then: 2. Should you define the getArea() method in the superclass GeometricObject? Or in the subclasses Circle and Rectangle? 3. If yes, Should the getArea() method be declared as abstract method in the superclass GeometricObject? Or as instant method? 4. Is declaring getArea() as abstract, would solve…
- Q/// In this part of the course work you are required to change the definition of the Item_in_Stock class to make it an abstract class and change the getItemCat(), getItemName() and getItemDescription() definitions to make them abstract methods. You are then required to design and implement three classes which are derived from Item_in_Stock class to fully demonstrate the concept of inheritance and polymorphism. Implementation of HP_Laptop class in part II should have given you an idea of inheritance and polymorphism. Three sub classes, one class against each category (Computers, Laptops and Accessories), should contain appropriate constructors, instance variables, setter and getters methods and overridden methods for getItemName(), getItemDescription() and get_Item_details() method. You should be creative and come up with your own ideas of sub-classes. The question: Write code in Java with all these classes implementation and a program called Polymorphism_works with member method…Develop a program (or find one on the internet) to exemplify and document dynamic binding). A parent and two or more child classes are needed. Shape, Triangle, Rectangle are common examples where Shape is the parent and Triangle and Rectangle are the child classes. Create a project for the program, add the parent and childs classes to it. Use main to exemplify dynamic binding by creating an array or ArrayList of the parent class type and filling it with objects of the child class types. Loop through the array and display all the objects in it by calling their toString method. Then create a method whose parameter is the parent class type. Have main call the method sending it the child types. What the method does is up to you. Heavily document this program since this is not a prescribed assignment. I want to read your words. So I want you telling me what it does, how it does it, and how it has anything to do with dynamic binding. Then using screen capture software, take…Inheritance, Polymorphism, ArrayLists, Throwing Exceptions The UML diagram below shows a set of classes designed to represent a music collection from 1995. The constructors and methods all function in the standard way, except: The equipmentRequired method should return “Record Player” or “CD Player” as appropriate.The getAlbum method of the NinetiesMusicCollection class accepts an index and returns the corresponding Album object. This method throws an IllegalArgumentException if the index is out of range. (This is the only exception you have to throw anywhere in your code.)In the NinetiesMusicCollection constructor, you can assume the ArrayList<Album> object passed as an argument is not null . Don’t worry about privacy leaks.Implement this set of classes in Java. Note the italics on the Class name “Album” and the method name “equipmentRequired” in the Album class.
- You are building a system for a Housing Society, such as Bahria Town. You are supposed to design a system that allows them to keep a record of how many blocks, sectors, streets, and houses the society has. Your system also generates unique names for blocks and sectors, and unique numbers of streets and houses. You must design the class structure yourself. 25 marks in this lab are for good class structure and good decisions regarding inheritance/composition.A society has many blocks, each block has many sectors, each sector has many streets, and each street has many houses. The society has a name, each block has a name (an alphabet), each sector has a name (an alphabet), each street has a number, and each house also has a unique house number.When your program starts:• It asks the user the name of the Society as well as the City in which it is located. Your program should be able to handle input that has more than one words.• Then, it asks the user how many blocks does this society has.…: Generalization is a type of class relationship.

- You need to perform following things to demonstrate the concept of abstract class. Step 1: Create the abstract class that has following methods. • Calculate the area of circle(Abstract method) • Calculate the area of triangle(Abstract method) • Calculate the area of rectangle(Method with implementation) Step 2: Create another class that extends above class and provide implementation of abstract methods. Step 3: Create the main method inside above class and display output of area of circle, area of triangle and area of rectangle. You need to submit the following things: • Java program with both the classes An output screenshot created using Microsoft WordDesign and implementation of Java (Draw UML) classes 1. Design a class named Bill to represent a square. 2. The class contains: • One data field called “Items” that defines the number of items. Another double data field called "price" defines the price. The default is 1.0. • no-arg constructor • constructor with parameters to create the invoice • method called getBill () that returns the item and price duplication. 3. Create a class and test a class (create three different objects and print the values of the variables and method)Java - Polymorphism Create a class named “Shape” that has the abstract methods getArea() and getPerimeter(). Create classes named “Rectangle”, “Square”, and “Circle”. Override the methods getArea() and getPerimeter() with the right equation in getting the area and perimeter. For rectangle, create attribute length and width. For square, side. For circle, radius. Inputs 1. Char input for Shape type (R/S/C) 2. Dimensions of specific type of Shape C 5 Sample Output Shape(R/S/C): R Length: 10 Width: 50 Area: 500.00 Perimeter: 120.00
