Provide implementation of interface with classes Window, Dialog. Override the base methods and call them polymorphically.
- Write a Program in Java Create an interface EnhancedShape that extends Shape and also requires a method public double perimeter( ) to be implemented by any class that uses the interface. (Note: Interfaces can inherit other interface just like a class by using extends keyword. Create a class file, an interface ehancedshape extends shape, and an interface shape file).only in java not in java c++ Create an interface EnhancedShape that extends Shape and also requires a method public double perimeter( ) to be implemented by any class that uses the interface. Create a class file, an interface ehancedshape extends shape, and an interface shape file.Implement the following tasks by using concepts of object-oriented programming (Java). i. Create a generic class with a type parameter that simulates drawing an item at random out of a box. This class could be used for simulating a random drawing. For example, the box might contain Strings representing names written on a slip of paper, or the box might contain Integers representing a random drawing for a lottery based on numeric lottery picks. Create an add method that allows the user of the class to add an object of the specified type along with an isEmpty method that determines whether or not the box is empty. Finally, your class should have a drawItem method that randomly selects an object from the box and returns it. If the user attempts to drawn an item out of an empty box, return null. Write a main method that tests your class.ii. The following is a short snippet of code that simulates rolling a 6-sided dice 100 times. There is an equal chance of rolling any digit from 1 to…
- Java code object Oriented; How to write a code of instance method type void with parameter of "Component component" that adds component into array. Using above method, how to code an instance method of type Component[] without parameter that returns new array with component that was added into array.Java program * Interfaces 1. Modify the class Rectangle to implement the Comparable interface, as shown in the following UML class diagrams. Apply the required changes in the class’s header.2. Then, in the Rectangle class override the method compareTo(), so if this object’s area is greater than the specified (given through the parameter) object’s area return 1, if it is less than return -1, and 0 otherwise. 3. Create a test class named Test2. Then complete the following tasks: a. Create an ArrayList and add to it 4 Rectangle objects with different width and height values. b. Print out the elements of the ArrayList. c. Sort the elements of the ArrayList using the static method sort of the class java.long.Collections. This would be possible only, if you implemented the method compareTo() correctly in the Rectangle class. d. After sorting the elements of the ArrayList, print the elements again. 4. Run the Test class. Here is the rectangle's class program public class Rectangle extends…A. Writing an Interface In this problem you will first write an interface and then modify classes to implement the interface. Write an interface, GeometricSolid, which has one method, volume. The volume method takes no arguments and returns a double. You are provided with three classes: Cylinder, Sphere, and RightCircularCone Modify the classes so that they implement the GeometricSolid interface. Supply the appropriate method for each class. You can use Google search to find the formula for the volume. Make sure that you use Math.PI in your calculations. Notice in InterfaceRunner that the objects are added to an ArrayList of GeometricSolids. since I couldn't fit all images with two screen shots I left the link here link: https://codecheck.it/files/18040616319p6jy6gzkdzuq08nmlp81251t
