the design of the class according to the following requirementsDesign ideas:? (1) Design a planar graphic abstract class (which provides methods for calculating the perimeter and area of the object) and a stereoscopic abstract class (provides a method for finding the surface area and volume of such objects)? (2) design ball, cylinder class, Cone class, Rectangle class, Triangle class, Circle class, respectively inherit the plane graph abstract class and the stereoscopic graphics abstract class.

Final ProjectWe encourage simulate a lift system with the stops (floors). We assume every customer takes 1 second to enter the lift and 1 second to leave. The lift ' s occupation space is a people with no weight limit. It takes seconds for the lift to travel between, nearby floors without discrimination for going up or going Down. An input file is given to which simulates the coming customer randomly. Here is a DEMO inputs: Customer ID Coming time Age
