In the Friday and the weekend, work to sneak in, looking at the Java cocurrent also by the way the Thread.Interrupt and Java 5 after the implementation of the Locksupport. Before introducing, let's throw a few questions. The relationship between Thread.Interrupt () method and Interruptedexception anomaly? is the interruptedexception exception triggered by the interrupt trigger? Thread.Interrupt () What state of the thread will interrupt the work? RUNNING or BLOCKING? General thread programming n

Many feedbacks were received when users posted the incident to hacker research websites, bitcoin mining websites, and other places. Some professionals pointed out that the script for hackers to implant wireless networks is actually Coinhive code, this is a JS engine dedicated for mining. Hackers can impla

Locksupport OverviewBasic thread blocking primitives for creating locks and other synchronization classes. The underlying threading block primitives used to create locks and other synchronization classes. This is the explanation in Java doc, and the following is a framework for a first in, out (first-in-first-out) non-reentrant lock class.The above code simple implementation of the lock function, mainly using the Locksupport Park and Unpark blocking and releasing threads, Atomicboolean CAS opera

For hang's problem, generally speaking, the following two kinds of reasons are common:1. Deadlock (cycle). For this hang, the problem will persist unless the loop is broken.2. A plug-in (blocker) process has blocked other processes after holding certain resources, and other processes have been
