- C# i need to Create an application named TurningDemo that creates instances of four classes: Page, Corner, Pancake, and Leaf. Create an interface named ITurnable that contains a single method named Turn(). The classes named Page, Corner, Pancake, and Leaf implement ITurnable. Create each class’s Turn() method to display an appropriate message. For example: The Page’s Turn() method should display You turn a page in a book.The Corner’s Turn() method should display You turn corners to go around the block.The Pancake's Turn() method should display You turn a pancake when it's done on one side.The Leaf's Turn() method should display A leaf turns colors in the fall i keep getting errors C# i need to Create an application named TurningDemo that creates instances of four classes: Page, Corner, Pancake, and Leaf.

Your MyStack.java will implement the IStack interface that is provided in the IStack.java file. You must implement your MyStack class as either a linked list or an array list (refer to your MyArrayList and MyLinkedList work). Your MyStack must not be arbitrarily limited to any fixed size at run-time. UML UML CLass Diagram: MyStack Structure of the Fields While there are no required fields for your MyStack class, you will need to decide what fields to implement. This decision will be largely based on your choice to implement this MyStack as either an array list or a linked list.

- Page < 32 of 41 You can override a private method defined in a subclass. (True/False)? ZOOM +#Testing Please test my code and see if it meet the follwing needs: The class should implement the Comparable interface. Circle one is less than Circle two if the radius of Circle one is less than the radius of Circle two. The two Circles are equal if they have the same radius. Circle one is larger than Circle two if its radius is larger. If circle One.compareTo circle Two <> 0 The Test Class displays a menu that allows the user to: Enter a Circle (the user only needs to enter the radius). Print all Circles (print the toString for each Circle in the ArrayList). Quit To adda a circle Cases: The ArrayList is empty The new circle is less than the first circle, add it at the beginning. The circle is greater than the last circle, add it at the end The new circle belongs somewhere in the middle. import java.lang.Math;public class Circle implements Comparable<Circle> {private double radius;public Circle(double radius) {this.radius = radius;}public double findArea()…Which is true? Group of answer choices A class can implement multiple interfaces A class can inherit from multiple classes A class can implement only one interface An interface can implement multiple classes
- 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.
