Background thread (daemon thread) and background thread daemon
There is a Thread that runs in the background, and its tasks provide services for other threads. Such threads are called "Daemon Threads ), also known as "daemon thread ".

Android main Thread and sub-Thread communication (Thread + handler)Android is based on Java, so it is also divided into main threads and subthreads!Main thread: implements business logic, UI rendering and updating, and connects sub-threads, similar to generals;Sub-thread: co
The concept of threading is used in Rt-thread instead of tasks. The two are similar, and I'm here to take his thread as a task to understand1 , Task handling :Dynamic task-related APIsCreate task: Rt_thread_create function that returns the task ID of the rt_thread_t type after the task is createdStart task after creation: Rt_thread_startupDelete Task: Rt_thread_deleteTask delay function: Rt_thread_delay del

Thread is also crazy ---- thread synchronization (1), ---- Thread SynchronizationPreface
When threads in the thread pool are blocked, the thread pool creates additional threads, and the memory resources required to create, destroy, and schedule threads are quite expensive. I
Python multi-thread programming (2): two ways to start a thread: python multi-thread programming
In Python, we mainly implement the thread and threading modules. The threading module of Python is encapsulated for thread and can be used more conveniently, therefore, we use th
What is the difference between the sleep () method of the thread class and the Wait () method of the object that allows the thread to pause execution?The Sleep () method (Hibernate) is a static method of the thread class (threads), which causes the current thread to pause execution for a specified time, giving the exec

The idle thread is a special thread in the system thread that has the lowest priority, and when no other threads in the system can run, the scheduler dispatches to the idle thread. Idle threads are usually a dead loop and are never suspended. The Rt-thread real-time operatin

Basic knowledge of programming languages: After basic concepts such as branch, selection, loop, and object orientation, we need to learn a certain degree about java advanced programming, it is inevitable to access multi-threaded development.
