This JSR extends and enhances JSR 195: Information Module Profile. The IMP-NG implementation depends upon CLDC 1.0. It is a strict subset of MIDP 2.0 that excludes MIDP 2.0 graphical display capabilities, resulting in a smaller footprint appropriate for Information Modules (IMs). Potential devices...
At the core of these new interfaces is SequencedCollection, which extends Collection and is ultimately implemented by all lists, some sets, and a few other data structures. It offers the addFirst, addLast, getFirst, getLast, removeFirst, and removeLast methods, which do what you’d expect. C...
