Process: The task executed by the computer
Thread: implementation of the mandate of the small multi-threaded
The computer then perform the process, and then at the same time can only make the cpu core to execute a process. Constitute a process has multiple threads, then the same time Cpu can handle only one thread.
The introduction of multi-threading
When a thread is executed cpu cpu to work, and thread needs to interact with software and hardware, this time cpu is idle
Reference multithreading can improve the efficiency of cpu
Create a multithreaded fashion ----- (Thead)
1. Thread class inheritance, override the run method (where the thread where the code logic, start method is called open thread. There is a bad place java is single inheritance can not inherit from other classes we inherited after Thread
, So we usually use the second method implements the interface
2. implement Runnable, run method override (logical threaded code), by constructing Thread class object implement Runnable interface class object, calling the start method of the thread opening
