Synchronization means multi threads access the same resource (data, variable ,etc) should not cause a corruption to it.If all methods of a class promise threading synchronization,we call that the class is "Thread Safe". Thread Safety ALL static…

JAVA线程状态.线程START方法源码.多线程.JAVA线程池.如何停止一个线程等多线程问题 这两个方法有点容易记混,这里就记录一下源码. Thread.interrupted()和Thread.currentThread().isInterrupted()区别 静态方法Thread.interrupted()源码如下: public static boolean interrupted() { return currentThread().isInterrupted(true); } 可以看…

Thread.sleep() The current thread changes state from Running to Waiting/Blocked as shown in the diagram below. Any other thread with reference to the thread currently sleeping (say t) can interrupt it calling t.interrupt() the call to sleep has to be…

线程这一概念,可以理解成进程中的一个小单元.这个单元是一个独立的执行单元,但是与进程中的其他线程共享进程中的内存单元. 由于Cpu资源是有限的,所以进程中的多个线程要抢占Cpu,这也导致进程中的多个线程交替执行. Thread.Sleep() 本身的含义是当前线程挂起一定时间. Thread.Sleep(0) MSDN上的解释是挂起此线程能使其他等待线程执行.这样的解释容易导致误解,我们可以这样理解,其实是让当前线程挂起,使得其他线程可以和当前线程再次的抢占Cpu资源. 代码示例: static…
