When I first came into contact with the concept of "Thread", I thought it was difficult to understand. I read many books and it took a long time to understand its true meaning. Now I will describe the "multithreading" that I understand as a beginner.
1: static methods cannot contain non-static members.
2: in a class, static variables are loaded with a memory space allocated. All the variable classes share one content. If any object modifies the value of static variables, the output values of
