In Java, 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. (Pentagon, Hexagon, and Octagon have equal sides). Also implement classes, IsoscelesTriangle, EquilateralTriangle, 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, use random geometric dimensions, and then out-put their area and perimeter. Note each class has its own file.
