(Geometry: Inside a polygon?) Write a program that prompts the user to enter the coordinates of five points from the command line. The first four points form a polygon, and the program displays the polygon and a text that indicates whether the fifth point is inside the polygon, as shown in Figure 14.51a. (Hint: Use the Node’s contains method to test whether a point is inside a node.)
