The event dispatching thread (EDT) is a background thread used in Java to process events from the Abstract Window Toolkit (AWT) graphical user interface event queue. It is an example of the generic concept of event-driven programming , that is popular in many other contexts than Java, for example, web browsers , or web servers .
If one thread executes its instructions out of order, then another thread might see the fact that those instructions were executed out of order, even if that did not affect the semantics of the first thread. For example, consider two threads with the following instructions, executing concurrently, where the variables x and y are both ...
A typical implementation model of Java-RMI using stub and skeleton objects. Java 2 SDK, Standard Edition, v1.2 removed the need for a skeleton. The Java Remote Method Invocation (Java RMI) is a Java API that performs remote method invocation, the object-oriented equivalent of remote procedure calls (RPC), with support for direct transfer of serialized Java classes and distributed garbage ...
M:N maps some M number of application threads onto some N number of kernel entities, [9] or "virtual processors." This is a compromise between kernel-level ("1:1") and user-level (" N :1") threading. In general, " M : N " threading systems are more complex to implement than either kernel or user threads, because changes to both kernel and user ...
Token-threaded code implements the thread as a list of indices into a table of operations; the index width is naturally chosen to be as small as possible for density and efficiency. 1 byte / 8-bits is the natural choice for ease of programming, but smaller sizes like 4-bits, or larger like 12 or 16 bits, can be used depending on the number of ...
[4] Each thread can be scheduled [5] on a different CPU core [6] or use time-slicing on a single hardware processor, or time-slicing on many hardware processors. There is no general solution to how Java threads are mapped to native OS threads. Every JVM implementation can do this differently. Each thread is associated with an instance of the ...
Real-time Java is a catch-all term for a combination of technologies that enables programmers to write programs that meet the demands of real-time systems in the Java programming language. Java's sophisticated memory management , native support for threading and concurrency, type safety , and relative simplicity have created a demand for its ...
The code uses the invokeLater(Runnable) method to invoke the constructor from the AWT event dispatching thread in order to ensure the code is executed in a thread-safe manner. Once the frame is displayed, exiting the main method does not cause the program to terminate because the event dispatching thread remains active until all of the Swing ...
