Write a static method that draws an arrow line from astartingpoint to an ending point in a pane using the following method header:public static void drawArrowLine(double startX, double startY,double endX, double endY, Pane pane)
Write a test program that randomly draws an arrow line, as shown in Figure.
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

- Create a method where a goblin will attack a zombie as long as the zombie has no health, otherwise the zombie is already dead. If the zombie has 0 or less health, the attack method should add 10 health to the zombie, bringing them closer to being alive so that they will be dead it should then return the zombies health. If the health of the zombie is positive the attack method should return "Zombie is alive, therefore it is not a zombie!". NOTE: This problem statement is extremely vague.
