Define a Polygon interface that has methods area() and perimeter(). Then implement classes for Triangle, Quadrilateral, Pentagon, Hexagon, and Octagon, which implement this interface, with the obvious meanings for the area() and perimeter() methods. Also implement classes, IsoscelesTriangle, Equilateral- Triangle, Rectangle, and Square, which have the appropriate inheritance relationships. Finally, write a simple user interface, which allows users to create polygons of the various types, input their geometric dimensions, and then out- put their area and perimeter. For extra effort, allow users to input polygons by specifying their vertex coordinates and be able to test if two such polygons are similar ORIGINAL WORKS ONLY
Write a Rectangle class to represent rectangles, with two data fields (width, height) and four methods (input data, display data, calculate and return area, calculate and return perimeter). Write another class to test all methods of the Rectangle class.
Implement the Shape hierarchy -- create an abstract class called Shape, which will be the parent class to TwoDimensionalShape and ThreeDimensionalShape. The classes Circle, Square, and Triangle should inherit from TwoDimensionalShape, while Sphere, Cube, and Tetrahedron should inherit from ThreeDimensionalShape.Each TwoDimensionalShape should have the methods getArea() and getPerimeter(), which calculate the area and perimeter of the shape, respectively. Every ThreeDimensionalShape should have the methods getArea() and getVolume(), which respectively calculate the surface area and volume of the shape. Every class should have a member variable containing its dimensions -- for example, the Circle class should have a member variable describing its radius, while the Triangle class should have three member variables describing the length of each side. Note that the Tetrahedron cass should describe a regular tetrahedron, and as such, should only have one member variable.Create a Driver class…

Modify the GeometricObject class to implement the Comparable interface and define a static max method in the GeometricObject class for finding the larger of two GeometricObject objects. Draw the UML diagram and implement the new GeometricObject class. Write a test program that uses the max method to find the larger of two circles, the larger of two rectangles.using java programming

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

Implement a class Moth that models a moth flying along a straight line. The moth has a position, which is the distance from a fixed origin. When the moth moves toward a point of light, its new position is halfway between its old position and the position of the light source. Supply a constructor Public Moth(double initialPosition) and methods pubc void moveToLight(double 1ightPosition) public double getpsition() Your MothTester should construct a moth, move it toward a couple of light sources, and check that the moth's position is as expected.
Create an interface Wheel with methods setWheels (int c) and getWheels () and a class Vehicle with abstract methods getColor () and getBrand (). Now, create a concrete class Taxi with additional method setDriver (String name) that inherits both Wheel and Vehicle. (Note: Concrete classes don’t have any abstract method)
