java thread interrupt

Parse the interrupt () method. For laruence, it's just a joke that a newbie has encountered such a problem, It is estimated that when you went to school, the teacher did not say well, and there was no specific explanation at all. This is what my java teacher did, Khan! ------ For details, seeCodeAnnotations ....... /** * Method for stopping a thread * @ A

A multithreaded Java program, until all threads have finished executing, the entire program will not exit. (Note that all non-background threads (Non-daemon thread) are executed, and if a thread executes the System.exit () method, the program exits. Sometimes, you want to abort a thread's execution, such as if you want to quit the program, or you want to cancel a

There are three methods in the Java Thread class, which are easy to confuse.(1) interrupt: sets the thread interruption status(2) isinterrupt: indicates whether the thread is interrupted.(3) interrupted: return the last interruption status of the

The stop () method is not recommended. The notorious stop () method of stopping a thread is no longer recommended. Why? When the stop () method is called on a thread object, the thread running on this thread object will immediately stop and throw a special threaddeath () exception. The "immediate" here is too "immediat

Interrupt may cause "thread interruption", but it cannot guarantee "thread interruption ". The "interrupt thread" here means "Stop thread", but why not "Stop thread? The

In the previous section, "Threading interrupts," we explained how to break an executing thread and what we had to do with thread in order to get disconnected. In general, we can use the interrupt mechanism described in the previous section. However, if the thread implements a complex algorithm that is assigned to multi

Description: The thread may need to stop on condition judgment while running, from the API to force terminate the thread with the Stop method, but this method is not recommended by the official, this is a method that expires, because if the thread is forced to stop, it is possible that some cleanup work will not be completed. Locked objects are also "unlocked", w

This article is a summary of the study of the article on the network, thank you for your selfless sharing.1 , if the thread implements some method that is divided by a complex algorithm, or if his method has recursive invocation, then we can use a better mechanism to control thread interruption. interruptedexception Exceptions are provided for this Java . When y

How to interrupt a running thread? Thread interruption means that the thread stops all ongoing operations before it completes the task, effectively suspending its current operation. Then, the thread waits for a new task, or continues to run to the next step. [Method 1] use

(), join (), and wait () methods are called, these methods throw interruptedexception. When this exception is caught in the catch block, the thread interrupt flag has been set to false, so t. isinterrupted (), thread. interrupted () is always false, T. isinterrupted and thread. the difference between interrupted () is

Sleep method also produces interruptedexception. Therefore, if the sleep method is called every time you finish some work, you do not need to check isinterrupted, but directly capture interruptedexcepti

Program Is simple. However, in front of programmers, multithreading presents a new set of difficulties. If it is not properly solved, it will lead to unexpected behavior and subtle and hard-to-find errors.In this article Article To address one of these challenges: How to interrupt a running thread. Background Interrupt means that the
