2017-2018-2 "Java Programming" Week 8 Learning Summary
------------------------------------------------------------------------------------------------------
Summary of tutorial content
1: Processes and threads
The concepts of both are related to the concept of programs.
Program: Static code, the blueprint for application software execution.
Process: a dynamic execution process of a program, which corresponds to the process of operating system loading from code --> execution --> execution and demise.
(The operating system can manage 1 or more processes at the same time and execute them in turn)
Thread: A smaller unit of a process, and the dynamic progress of a process will generate multiple threads. Threads also have a dynamic slave
The process of birth to death. Both belong to an inclusive relationship.
2: Main thread
A thread started after the main method is found, responsible for executing the main method, called "main thread".
（1 && 2）
① Four states of the thread
New --> Run --> Interrupt --> Die
(Because the processes are switched in turn, they can all occupy the CPU, which will also cause thread interruptions.)
② Common methods of thread
1: start() 2:run() 3: sleep(int millsecond) 4:isAlive() 5:currentThread() 6:interrupt
3: Thread class
① The construction method of using Thread to create a thread: Thread(Runnable target)
(The parameter is the interface of the Runnable type, for the actual example, please refer to Example12_3.java)
