- Implement using Java Create an interface that shall have 2 methods and one string type attribute, also create an implementation class of the interface that shall define both methods (you can print YOUR favorite quote in each method body).class B extends A {} is the correct way to implement an interface in Java. True or False?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.
- only in java not in java c++ 1. Define an interface named Shape with a single method named area that calculates the area of the geometric shape: public double area(); 2. Implement the Shape interface for Rectangle, Circle and Triangle class. 3. Implement a class CalculateAreas that has a function that takes shape type array of objects and builds an array of (double values) values for each corresponding shapesSubject: Java Programming Question#3: Define an interface Frame with methods paint, redraw and fields width, height, title. Provide implementation of interface with classes Window, Dialog. Override the base methods and call them polymorphically.From Big Java 6th edition P9.7: "In this problem, you will model a circuit consisting of an arbitrary configuration of resistors. Provide a superclass Circuit with a instance method getResistance. Provide a subclass Resistor representing a single resistor. Provide subclasses Serial and Parallel, each of which contains an ArrayList<Circuit>. A Serial circuit models a series of circuits, each of which can be a single resistor or another circuit. Similarly, a Parallel circuit models a set of circuits in parallel; using Ohm's Law to compute the combined ressistance." I managed to create appropriate subclasses off of the Circuit superclass. But from here, I'm stuck! How do I compute the combined resistance? and how would I get the method to read the values off of the ArrayList<Circuit>? And does that Circuit refer to the Circuit Class I created, or would that require input for resister amounts?
- Implement the Deque interface given below using java,util.ArrayList as an adaptee. Implement as a class adapter. Your class must not have any unnecessary methods. import java.util.*; public interface Deque { public boolean addAtTail(Object value); public Object removeElementAtTail(); public Object getElementAtTail(); public boolean addAtHead(Object value); public Object removeElementAtHead(); public Object getElementAtHead(); public int size(); public void clear(); public Iterator iterator(); } Note: Don't copy from online sources. Thank you.Write a Program in java Define an interface named Shape with a single method named area that calculates the area of the geometric shape: public double area(); Implement the Shape interface for Rectangle, Circle and Triangle class. Implement a class CalculateAreas that has a function that takes shape type array of objects and builds an array of (double values) values for each corresponding shapesGive the names of the two methods that we have to have to implement interface Iterator as shown in RED below.
- Create an interface MessageDecoder that has a single abstract method decode(cipherText), where cipherText is the message to be decoded.The method will returnthe decoded message. Create a class SubstitutionCipher that implements the interface MessageDecoder as described above. The constructorshould have one parameter called shift. Define the method decode so that each letter is shifted by the value in the shif. For example, if shift is 3, a will be replaced by d, b will be replaced bt e, c will be replaced by f, and so on. Hint: You may wish to define a private methodthat shifts a single character. Create a class ShuffleCipher that implements the interface MessageDecoder. The constructor should haveone parameter called n. Define the method decode so that the message is shuffledn times.To perform one shuffle, split the message in half and then take the charactersfrom each half alternatively. For example, if the messsage is "abcdefghi", the halves are "abcde" and "fghi". The shuffled…Java provides one interface to sort objects of user defined types. What is the name of this interface type. Use an example to describe how to implement this interface.write program in java Design an abstract class GeometricObject. GeometricObject must ensure that its children must implement calcArea() method. Design RectangleYourRegNo and CircleYourName Classes as children of GeometricObject class with overridden toString() method to return “Rectangle with w Width and h Height is drawn” OR “Circle with r Radius is drawn”. The attributes of Rectangle are length, width. The attribute of Circle is radius Hint: Area of circle=πr2 , Area of rectangle= width*length
