How to program boards in java?

Question

Java

Hello. I would like to ask one question. How to program boards in java? My friend and I decided to start creating robotics, he cooks boards, and I program them. Here I have a question. Never encountered this before. For example, everything should work like this: the board is connected via USB to a PC and controlled using software. It is desirable to explain in more detail and throw off the link to the lessons on board programming.
