1. Write the following method that returns the intersecting point between two lines (p1, p2) and (p3, p4):
public static Point2D getIntersecting Point (
Point 2D pl, Point2D p2, Point 2D 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.)
Enter x1, yl, x2, y2, x3, y3, x4, y4: 2 2 5 -1.0 4.0 2.0 -1.0 -2.0
The intersecting point is at (2.88889, 1.1111)
Enter x1, yl, x2, y2, x3, y3, x4, y4: 2 2 7 6.0 4.0 2.0 -1.0 -2.0
The two lines are parallel
