Organizations are attracted to Java because the language has proven more economical than C and C++. Companies that have made the switch to Java typically find that they are twice as productive during development of new functionality and five to ten times as productive during reuse of existing code. Organizations that develop in Java also observe decreased software error rates, increased software reuse and longevity, and improved recruitment of competent developers. Special hard real-time Java development practices enable proofs of resource needs and determinism. Early analysis demonstrates that the hard real-time Java platform runs in less than a tenth the memory footprint and up to three times faster than traditional Java for typical hard real-time tasks. Determinism is on par with typical C code, offering more than a 20-fold improvement over the timing predictability of traditional Java.
