In any case, the mechanism is not guaranteed to cause the thread to stop: the thread s code could be written in a way to trap such exceptions and ignore them. Because of these problems, Sun chose to deprecate this feature of Java [16]. Instead, Sun recommends that running threads be canceled using the Thread.interrupt( mechanism, which is safe because it causes the thread to be interrupted only at well defined points in the code. Certain library routines can generate an InterruptedException, which is a checked exception ....

....to be solved, rather than a means to better performance. These kinds of computations do not benefit from parallel loops, and are better expressed as separate routines executing concurrently rather than one loop executing in parallel. The kind of concurrency normally provided by Java Threads [15] or Ada tasks [2] is probably more appropriate for this kind of system. 2 Parallel Loops A parallel loop is a for loop in which the iterations of the loop execute concurrently rather than sequentially. When the program reaches a parallel loop it spawns multiple threads to execute the iterations ....

....and it is the responsibility of the programmer to make sure that the thread exits cleanly. Although it is possible for code to ignore the interruption and continue running, this is not worse than the Thread.stop( method, which cannot provide this guarantee either, and is much harder to use safely [15]. For these reasons, we attempt to terminate running iterations of the loop using the interrupt mechanism. Because poorly written code could ignore the interrupt mechanism, the semantics cannot provide a guarantee that canceled iterations will terminate promptly, or even that they will terminate ....

This construct for expressing concurrency is often implemented in a library rather than as a syntactic construct of the language itself, as is done in the POSIX Threads interface [2] the Win32 API [3] and Java [4].

....important goal is to provide support for applications that are not originally developed for group usage, i.e. collaboration transparent applications. We target a particular class of collaboration transparent applications Java applications or applets that comply with the JavaBeans specification [24]. The reason for focusing on JavaBeans is that JavaBeans, along with ActiveX controls from Microsoft [10] represent a strong software industry trend towards standardizing software development through reusable software components. Components enable rapid application development using third party ....

....most common events are input device (keyboard, mouse) events. Our initial approach [18] was based on the property of Java Development Kit (JDK) version 1. 1 event model that any object can register as an event listener to the event sources and all listeners get notified upon the event occurrence [24]. We call this approach bottom up since it assumes knowledge about the application s internal structure. Unfortunately, while we can capture events this way, we cannot intercept them before they get executed locally and thus cannot provide any type of concurrency control. The approach works for ....

Currently, component implementation is driven by the selection of a particular component framework, such as JavaBeans [13], Component Object Model (COM) 12] or CORBA [5] A component belonging to one of these frameworks must embed the appropriate mechanisms to belong to the framework, so in a sense embedding need not be a controversial topic.

Using the buttons, a user can push (pop) an integer on (off) a stack; top places the topmost element of the stack into a textfield and quit exits.
