How and where to show a Java program to give a clear idea about the code and the question about it in the community?

Question

Java

Hello!
I have a small question about the code. To demonstrate the subject of the problem, you need the responder to run the code at home. How should such a question be framed?

Answer 1

In the form of a github repository ready to be launched after entering two or three commands. But the chance to get an answer to a question, the code of which cannot be given in the form of a minimal, self-sufficient and reproducible example , is scanty.
