Write a Java program that prompts the user to enter an integer n, which represents the number of vertices (nodes) of Kn. The program displays the complete graph Kn as shown in the sample run. The program uses a method called showKn that receives n as parameter, displays the complete graph and a legend on the top left corner indicating the number of vertices. The graph should be centered to the window and its radius should be 1/4 of the length of the windows' diagonal. You should also use property binding so that if the user resizes the window, the graph will be redrawn. Please refer to the attached sample run for n = 20. Please submit zip file with your entire Eclipse project. Should be written in java using javaFx
