please explain how to create class and how to write the code.

thank you.

1. Write the following method that returns the intersecting point between two lines (p1,p2) and (p3,p4) : public static Point2D getintersectingPoint( Point2D p1, Point2D p2, Point2D p3, Point2D p4); The method returns null if the two lines are parallel. Write a test program that prompts the user to enter three points and displays the center point. Here is a sample run. (Hint: for finding the intersecting point between two lines, see Programming Exercise 8.31.) x1,y1,x2,y2,x3,y3,x4,y4:2251.04.02.01.02.0 The intersecting point is at (2.88889,1.1111) x1,y1,x2,y2,x3,y3,x4,y4:2276.04.02.01.02.0 eentericon> The two lines are parallel
