Java Features -- It's Multithreaded

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.

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.
