Java multi-thread (2) multi-thread lock mechanism and java multi-thread lock mechanism When two threads access a class at the same time, some problems may occur. Concurrent thread re-entry may cause memory leakage, uncontrollable

[JAVA concurrency] basic thread mechanism, java concurrent threadBasic thread Mechanism A program can be divided into multiple independent tasks, and each independent task can be executed by a thread; A process can contain several threads, that is, a number of concurrent tas

Java multi-thread (4) thread pool and java multi-thread pool A good software does not randomly create and destroy threads, because it takes a lot of CPU time and requires a lot of interaction with the memory. Therefore, JDK 5 proposes to use the

In the previous blog post, the use of the Member method interrupt () was introduced, and the last part of the article went on to describe the remaining two methods related to interrupts.2. Member method new Thread (). isinterrupted ()It is common to use the Thread.CurrentThread (). isinterrupted () method to determine whether a thread has been sent an

if the operation has not been completed. A Futuretask object can be wrapped on an object that calls callable and runnable, because Futuretask also calls the Runnable interface so it can be submitted to executor for execution.What is the difference between interrupted and Isinterruptedd methods in Java? The main difference between interrupted () and isinterrupted () is that the former clears the interrupt s

Interrupt processing In Java programs, you need to handle interruptedexception when you use a blocking method such as Thread.Sleep () or Blockingqueue.take (). For this exception, there are usually 2 scenarios for processing. 1. Passing Exceptions: Passing exceptions to the caller of the method. Examples are as follows: blockingqueue 2. Restore exceptions: In most cases, exceptions can be passed, but in

blocking interruption may be simply solved by the problems in our program, but this solution may provide a poor user experience. We can use the thread to interrupt the blocked thread. the following code is used to implement the interrupt () method: Package Cn.com. sxia; Import J
