(...or any other IO method that wraps read(), like BufferedReader.readLine(). Calling thread.interrupt() does nothing.) You can't. That's the way it's supposed to work. One workaround is to use ...more

Well first theres nothing you can do explicitly for this. This IS the way it works. Multiple client calls to the same object are NOT queued up but concurrent method invocations on an RMI object ar...more

I am on the Java-Threads mailing list, hosted at University of Kent at Canterbury (java-threads@ukc.ac.uk). This is a fairly quiet list but the quality of advice is typically very good. Broadly, t...more

The PipedInputStream/PipedReader and PipedOutputStream/PipedWriter streams provide synchronized I/O across threads, from within one class or multiple classes. The following example demonstrates th...more

[Short answer: threads are lightweight, programs (aka processes or tasks) are heavyweight. -Alex] Lightweight and heavyweight processes refer the mechanics of a multi-processing system. In a l...more

Starvation is when the Java runtime (JVM) doesn't allocate time to a thread to execute. This may be due to a poor scheduling algorithm (like green Threads under Solaris, where a for loop from 1 to...more

Thread.sleep() sends the current thread into the "Not Runnable" state for some amount of time. The thread keeps the monitors it has aquired -- i.e. if the thread is currently in a synchr...more

Sign your code and enable UniversalThreadGroupAccess. PrivilegeManager.enablePrivilege("UniversalThreadGroupAccess"); For a full list of the targets and what tasks they provide access t...more

Use thread.setDaemon(true) to tell the JVM to make the thread a daemon thread. According to Webster's, a daemon (variant of demon) is an attendant power or spirit. Daemon threads are typically...more

The wait() and notify() methods are object-specific. The wait() method suspends the current thread of execution, and tells the object to keep track of the suspended thread. The notify() method tel...more

If you create threads in a ThreadGroup object, they may be controlled simultaneously with the member functions of said object.

The keyword synchronized is used to acquire a exclusive monitor lock on an object. It can be used to mark either a method or a block of code. In both cases, it means to acquire a lock for the dur...more

A thread is created by the VM behind the scenes during a call to the start() method. It begins its life inside the run() method of the thread subclass instance whose start() method was called. more

Extending the Thread class will make your class unable to extend other classes, because of the single inheritence feature in JAVA. However, this will give you a simpler code structure. If you impl...more
