Java model offers preemptive multithreading, implemented in terms of the Thread class. Thread methods offer a set of synchronization primitives based on monitor and conditional variable paradigm by C.A.R. Hoare. Java threads inherit some features from the pioneering Cedar/Mesa System by Xerox Park that gave birth to Macintosh and object-oriented programming.
-
Threads should run in parallel on multi-processor shared memory machines
-
Threads can support full parallel computing on such architectures

A typical use of Java multithreading in applet programming is to have several independent but related simulations (e.g. various sorting algorithms), running concurrently in an applet window.
-
Multithreading is also used internally by the browser to handle multiple document dynamics.
-
I.e. base use is to keep computing while some threads wait on I/O

Java threads don't have built-in point-to-point communication primitives. Various thread communication environments can be provided by coupling the thread and network protocol objects.
