Create a Java program that has the following:
Inheritance - Create a superclass and one or more subclasses that inherit properties and methods from the superclass.
Polymorphism - Show polymorphism by using method overriding and method overloading.
Provide an example of runtime polymorphism by creating objects of the subclasses and calling overridden methods.
Encapsulation - Demonstrate the concept of encapsulation by applying access modifiers (private, protected, public) appropriately in your program.
Abstraction - Utilize abstract classes and methods in your program to illustrate abstraction.
Show examples of the following words: super, this, static, final

- If we want our classes to be open to extension, we may have to reorganize our dependencies to depend on __________ instead of concrete classes. (in Java) The Single Responsibility Principle (SRP)The Open-Closed Principle (OCP)The Liskov Substitution Principle (LSP)The Interface Segregation Principle (ISP)The Dependency Inversion Principle (DIP)arrow_forwardTrue or false?(a) Every object is an instance of the object class.(b) If a class does not extend a superclass explicitly, it extends object by default.arrow_forwardInheritance, 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.arrow_forward
