Java multi-thread ultra-Detailed summary-Alibaba Daniel stayed up late, Alibaba DanielIntroduction If you are still confused about what a thread is and what a process is, Google the two concepts, because they are not within the scope of this article. Multithreading has only one purpose, that is, to make better use of cpu resources, because all multithreaded code

different I/O. A common way is InputStream's read () method, which blocks until a byte of data is read from the stream, it can block indefinitely, and therefore cannot specify a time-out;4, a thread can also block waiting for exclusive access to an object lock (that is, to wait for a lock that the synchronized statement must have blocked).Note that not all blocking states are interruptible, the first two of the above blocking states can be interrupte

As a thread container, BlockingQueue can provide powerful guarantee for thread synchronization. The main methods used include:[Java]Add (E o); // add the specified element to this queue (if feasible immediately). true is returned upon success. In other cases, IllegalStateException is thrown.DrainTo (Collection DrainTo (Collection Offer (E o); // Insert the specif

It's easy to start a thread in Java, and usually we wait until the end of the task to let the thread stop itself. But sometimes you need to cancel them while the task is running, so that the thread ends quickly. There is no mechanism available for this java. But we can do th
