Chapter 22, Problem 22.13PE

Program Plan Intro

Program to create the polygon through convex hull animation

Program Plan:

• Import the required java packages.
• Create the class named “Exercise22_13”,
• In the main() function,
  • Declare the class “View” to draw and fill the color of rectangles.
  • Raise the event inside the rectangle to set the event by right clicking or left clicking the mouse.
  • Call the function drawNewPolygon() to draw the polygon with the respective points.
• In the drawNewPolygon() method,
  • Retrieve all the points from the array list.
  • Execute the for loop to add the points inside the circle.
  • Clear the polygon.
  • If the size of the points is greater than 3, then find out the centre position of the co-ordinates of “x” and “y” and call the function getConvexHull() to add the array list of points.
