How do I call the network tables

Hi I’m from team 4381 and using Java, we are using the robo realm to do our image processing I can get values onto the outline viewer. Yes it is client sides so they are both connected to the robot, I’m just wondering how do I pull the number off the network tables and onto the smartdashbord so I can create code to do stuff with it.

Thanks,
