Real-Time Programming in Java

Some of Java's defining characteristics — such as Object -Oriented Programming, dynamic loading, and garbage collection — although advantages in general, have proved to be obstacles to the language's spread in the domain of real -time system development. A real -time program's time and space requirements must be predictable, but Java's dynamic underpinnings interfere with that goal. Real -time garbage collection, despite some encouraging recent progress, is still more a research topic than a practical technology. Java's loose semantics for thread scheduling make it difficult for a developer to ensure that periodic threads will meet their deadlines, and that priority inversions will be avoided.
