I am worked in project that I have to do simulator to traffi

Solution

You can use swing for this purpose, since I don\'t have much description of your project I am going to share my sample code of a project on which I worked long time back then. Try to run it and understand the concept may be that can help in your project. By the way this project which I am going to share is a code of bouncy balls objects moving.

In this project swingBot is used for moving the object. I hope this will help you in your project.
