Real-Time Java™ Platform Programming

Major Features of the Specification

The Real-Time Specification for Java enhances the Java specification in six ways:

1. It adds real-time threads. These threads have scheduling attributes that are more carefully defined than is the scheduling for ordinary Java threads.

2. It adds tools and mechanisms that help programmers write Java code that does not need garbage collection.
