Object-Oriented Programming OvalDraw Plus (Java code) Summary: Create a graphical application with Java that that draws an oval Prerequisites: Java, VS Code, and Terminal Create a graphical Java application that runs on Microsoft Windows and MacOS that draws an oval centered in the main application window when the programming starts. The oval should automatically resize and reposition itself when the window is resized. In this activity you will start with our OvalDraw application in our sample code, review the code, and then make incremental improvements to the application. Be sure to make the resulting application uniquely your own by adding standard comments at the top application (i.e. your name, class, etc.), changing the names of variables, and adding small features. Finally, be sure to save your work as you will often be asked to submit it as part of an assignment. Be sure to review the example OvalDraw project in the Java section of our example code repository. Requirement 1:…

Object adapters and class adapters each provide a unique function. These concepts are also significant due to the significance that you attach to them.

What benefits are provided by interfaces? Is it not easier to create objects that belong to a certain class?

Library Information System Design and Testing Library Item Class Design and TestingDesign a class that holds the Library Item Information, with item name, author, publisher. Write appropriate accessor and mutator methods. Also, write a tester program(Console and GUI Program) that creates three instances/objects of the Library Items class.   Extending Library Item Class Library and Book Classes: Extend the Library Item class in (1) with a Book class with data attributes for a book’s title, author, publisher and an additional attributes as number of pages, and a Boolean data attribute indicating whether there is both hard copy as well as eBook version of the book. Demonstrate Book Class in a Tester Program (Console and GUI Program) with an object of Book class.
