Java中每个类的线程（多线程？）

Question

I have a question. I am planning on creating a program which would have multiple classes(for each object like cars/player/enemies etc), and I wanted to ask, is it a good idea to create a thread in each of those classes? I read that some Java VM support around 6500 threads, but would a mediocore laptop be able to support about 10-20 of them?

Answer 1

I think you should step back and do some more thinking/learning here.

You see, threads are a programming mean used to enable "parallel" processing on some level. They are not inherently "good" or "bad".

In other words: you don't just "use one thread per class/object" because you could do so.

You would only do that because you have a problem to solve where doing so would make sense .

And generally spoken: such an idea doesn't make much sense in the first place.

You see, the idea of "each object/class" having its "own activity" that "drives" them is addressed by frameworks such as akka . And be assured: whatever you could come up with - such products such as akka would be more robust, more performant, more everything ...

The real answer here; as said: you should step back and first understand your actual requirements. And then you carefully look into existing technologies in order to design a reliable, robust solution.

As for example, there are such things as Threadpools or the whole ExecutorService infrastructure that allow you to do things in parallel without the effort of managing Thread objects yourself. You should very much prefer to build on something like that, instead of just pushing "bare metal" threads into your classes.
