Java Vision Webcam

Hello,
I am very new to FRC and looking for how to get webcam’s vision to get hooked to driver station(purpose: livestream). How should i begin with what code and at where in eclipse folder of robot.java should i place it in? Thank you!

Here is the WPILib screensteps documentation for a camera server with example code:
