• #3: ��the Java Compiler��TM��product generatesbytecodes--an��architecture neutral��intermediate format designed to transport code efficiently to multiple hardware and software platforms. The interpreted nature of Java technology solves both the binary distribution problem and the version problem; the same Java programming language byte codes will run on any platform.Architecture neutrality is just one part of a truly��portable��system. Java technology takes portability a stage further by being strict in its definition of the basic language. Java technology puts a stake in the ground and specifies the sizes of its basic data types and the behavior of its arithmetic operators. Your programs are the same on every platform--there are no data type incompatibilities across hardware and software architectures. ��The��automatic garbage collector��runs as a low-priority background thread, ensuring a high probability that memory is available when required, leading to better performance.��Java technology's��multithreading��capability provides the means to build applications with many concurrent threads of activity. Multithreading thus results in a high degree of interactivity for the end user. While the Java Compiler is strict in its compile-time static checking, the language and run-time system are��dynamic��in their linking stages. Classes are linked only as needed. New code modules can be linked in on demand from a variety of sources, even from sources across a network.
