When to use Runnable and Callable
When it comes to Java, we have to talk about multi-threading. Even if you don’t want to say it, the interviewer has to let you say it, right? When it comes to multi-threading, threads are not allowed to be mentioned (isn’t this nonsense). When it comes to threads, we have to talk about Runnable and […]
The relationship between Callable, Runnable, Future and FutureTask
There are two ways to create a thread: inherit the Thread class or implement the Runnable interface and override the run method. The Thread class itself also implements the Runnable interface. Runnable interface source code: The run method has no return value, so the Callable interface appeared in JDK1.5 Relationship class diagram Callable Callable interface […]
Refresh the page without any sense (with runnable front-end and back-end source code, front-end vue, back-end node)
1. Foreword Imagine that you are browsing pages normally on the web. Suddenly a window pops up, telling you that your login is invalid and jumping back to the login page, asking you to log in again. Are you annoyed. At this time, the role of senseless refresh is reflected. 2. Plan 2.1 redis set […]
Multi-threading in one pot (Runnable, Callable, Thread, Future, FutureTask)
Multi-threading in one pot (Thread, Runnable, Callable, Future, FutureTask) In the multi-thread execution cycle, the basic process can be briefly divided into (new execution task->create task process->task assembly process->start/execute thread->get result/status). The processes responsible for various elements are as follows Show: Element name/process New execution task Create task process Task assembly process Start/execute thread Get […]
Use of QThreadPool and QRunnable for Qt multithreaded programming
When it comes to threads, you usually think of QThread, but in fact, there are many ways to create threads in Qt. Here we mainly introduce one of them, QRunnable. The usage of QRunnable and QThread is somewhat different, and the usage scenarios are also different. To introduce the usage, usage scenarios and precautions of […]

Qt thread pool QThreadPool class, QRunnable class
QThreadPool class Used to manage QThreads. All functions in this class are thread-safe. Main attributes: 1. activeThreadCount: This attribute indicates the number of active threads in the thread pool, which is called by activeThreadCount(). 2. expiryTimeout: The time the thread is alive. Threads with no expiryTimeout milliseconds set will automatically exit, and such threads will […]
