Java Supplements is a free library of utility classes which extends and enhances the functionality of the classes provided by the normal Java API. It provides robust and reliable code for doing many of the tasks which Java developers commonly find themselves writing code for again and again, such as catching InterruptedExceptions on Thread.sleep() calls or reading files into a byte array.
Gos4j is a way of organising processing priorities based on goals. Each goal is prioritised to be processed based on its time to complete and its progress towards that goal. Deadlines are used to act as the target completion time for a goal, and can be expressed in either relative or absolute terms. It can be used to support an unknown processing environment with real time constraints. A typical example of this would be in an application programming set-up, where user code would run alongside your code, and so fixed priority scheduling may not be efficient. Gos4j can easily reschedule threads to meet as many of the specified constraints as possible, so overall performance will degrade gracefully and conflicting time constraints will be handled equitably.
