title: How to draw an image over another image?
body: <p>I have a Java project that's about traffic network simulation in a random city, I've managed to figure out a way to implement this project, so I divided each intersection into a section which is basically an extended JPanel class (named Carrefour)...everything works well until I got stuck with how to draw vehicles and make them pass through roads.</p>
  
  <p>So my problem is how to draw an image (vehicle image) over an another image (road)?</p>
