On the previous page, we looked at how to construct a thread in Java, via the Runnable and Thread objects. We mentioned that the Thread class provides control over threads. So on this page, we take a high-level look at the most important methods on this class. ...
Both methods are synchronized, so that in theory a call to addJob() can't be run while the stop request method is running and waiting for the thread to finish: public class Processor extends Thread { private volatile boolean stopRequested; public synchronized void requestStopAndWaitToFinish() ...
Methods Deprecated injava.lang.Threadas ofJDK 10 It now appears that two of the threeThreadmethods that are deprecatedandmarked for removal will be removed with JDK 11. Both methodsThread.destroy()andThread.stop(Throwable)should be completely removed as of JDK 11. Thedestroy()method has never ...

JavaFinalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. (Inherited from Object) Notify() Wakes up a single thread that is waiting on this object's monitor. (Inherited from Object) NotifyAll() Wakes...

First, it is not possible for two invocations of synchronized methods on the same object to interleave. When one thread is executing a synchronized method for an object, all other threads that invoke synchronized methods for the same object block (suspend execution) until the first thread is don...
同步方法是一种简单的防止线程冲突(thread interference)和线程一致性错误(memory consistency errors)的策略:如果一个对象对多个对象可见。所有针对对象变量的读写都会通过同步方法。(一个重要的例外:final fields,在线程构造完毕后不能被更改,一旦对象被构造,能够通过非同步方法访问)。这种策略是有效的,但是会存在活性(...
