We can create objects of type Shape. We can create objects of type Square. We can create objects of type Triangle. Square needs to be an abstract class because it does not define the numberSides method.. The class header for Square should not have the word abstract in it.

Write the constructor method for class Circle which is a subclass of Shape class. Class Shape has one attribute (color) and one constructor (with one parameter). Class circle has attribute for radius.
1. Define a class named Randomwalker. A Randomwalker object should keep track of its (x, y) location. All walkers start at the coordinates (0, 0). When a walker is asked to move, it randomly moves either left, right, up or down. Each of these four moves should occur with equal probability. The resulting behavior is known as a "random walk." (A 2-dimensional random walk example is pictured at right.) Each Randomwal ker object should have the following public methods. You may add whatever fields or methods you feel are necessary to implement these methods: move () Instructs this random walker to randomly make one of the 4 possible moves (up, down, left, or right). getX () Returns this random walker's current x-coordinate. getY () Returns this random walker's current y-coordinate. getsters () Returns the number of steps this random walker has taken.

a:) Define a Polygon interface that has methods area() and perimeter(). b:) Then implement classes for Triangle, Quadrilateral, Pentagon, Hexagon, and Octagon, which implement this interface, with the obvious meanings for the area() and perimeter() methods. c:) Implement classes, IsoscelesTriangle, Equilateral-Triangle, Rectangle, and Square, which have the appropriate inheritance relationships. d:) Write a simple user interface, which allows users to create polygons of the various types, input their geometric dimensions, and then output their area and perimeter. e:) For extra effort, allow users to input polygons by specifying their vertex coordinates and be able to test if two such polygons are similar. using all a to e parts develop a program
