I have a set of points which define a route and I must draw them so a vehicle's moving direction is denoted. The points may be from a curve and I need to draw some arrows. I want to draw arrows on the route to define which arrow vehicle goes. I have a mapviewr java applet and the last I must do is this work, I want to define arrows on every 10 points on the route.
A thing like this: alt text http://img517.yfrog.com/img517/7690/schermafbeelding2010032.png

I would suggest you to take a look at Java2D shapes :they allow you to define any kind of ... well ... shape and draw them on a given path. You can take a look at this tutorial or at Sun tutorial.

In addition to what Riduidel said you should also try to get the angle that results from the intersection of the line with OX. Using that angle you could calculate a transformation matrix to draw the arraws neatly aligned to the line.
