Understanding threads and processes correctly

These concepts I believe there are a lot of Baidu, here, I am a programmer's point of view.

Process is a static concept, the machine is running a thread, a process can contain multiple threads.

An EXE file, class file is a process, at a point in time, a CPU on only one thread,

But it's very fast, so it's like there are multiple processes running at the same time.

In Java, there are two ways to start a new thread:

1. Inherit from the thread class. 2. Implement Runnable Interface (refer to other information, not detailed here)
