Modeling Java Threads in UML

Abstract

Modern programming languages such as Java facilitate the use of concurrent threads of control within computer applications. Considering concurrency is an important prerequisite for the adequate realization of object-oriented ideas, since real world objects usually operate in parallel. This brings up the requirement to be able to express concurrency issues already in design models, which precede implementation activities. The paper examines the possibilities of modeling Java threads using the Unified Modeling Language (UML). UML is the official industry standard for object-oriented modeling as defined by the Object Management Group (OMG).
