The heart of the Java Platform is the concept of a "virtual machine" that carries out Java bytecode programs. This bytecode is the same despite what hardware or operating system the program is running under. There is a JIT (just-in-time compilation) compiler inside the Java Virtual Machine, or JVM. The JIT compiler converts the Java bytecode into native processor instructions at run-time and caches the native code in memory during the tome of the execution.
The use of bytecode as an intermediary language that allows Java programs to run on any platform that has a virtual machine accessible. The use of a JIT compiler means that the applications in Java, after a small delay throughout loading and once they have "warmed up" by being all or mostly JIT-compiled, tend to run about as speed as native programs. Because JRE version 1.2, Sun's JVM execution has included a just-in-time compiler as an alternative of an interpreter.

Difference between C and C++ programming language
This C language was the C++ predecessor. Even though not actually being more powerful than C, C++ lets the programmers to more easily deal with and operate with Objects, using an OOP (Object Oriented Programming) concept.
The C++ allows the programmer to create classes, which are a bit alike to C structures. Although it is possible to apply anything which C++ could implement in C, C++ aids to standardize a means in which objects are created and managed, whereas the C programmer who implements the same system has alot of liberty on how to really implement the internals, and the style among programmers will differ alot on the design choices made in a program.
In C, some will choose the handler-type, where a main function initializes a handler, and that handler can be provided to other functions of the library as an object to manage on/through. Others will even want to have that handler link all the associated function pointers within it which then must be called using a convention closer to C++.

A short note on the history of Honda
The Honda VTR1000F is a motorcycle invented by Honda. In 1997 Honda started producing a street-oriented GT motorcycle using a traditionally important name: Superhawk. The earlier (60's) Superhawk was a parallel twin motorcycle that Robert M. Pirsig rode in "Zen and the Art of Motorcycle Maintenance". The original Superhawk was a profitable success, that's why the name is being recycled. The latest Superhawk was introduced after the Ducati 916 made V-twin sport bikes well-liked again. The new Superhawk uses an all new 90 degree V-twin. The bike introduced numerous new design concepts for example the "pivotless frame", side radiators, single casting engine case, involving rods with cap screws rather than nuts, and the biggest carburetors Honda ever put on a motorcycle. "Pivotless frame" intended that engine was a stressed member with the swing arm bolted straightforwardly to the engine. The bike was come into public in 1997 as an early release 1998 model year. One motorcycle magazine recommended (circa 2000) that this bike was the fastest 0-60 mph production bike at that time. A racing version of the bike was anticipated from Honda. The Honda produced in 2000 the RVT1000R (RC51) recognized outside the United States as the VTR1000SP, though the bike had only four engine parts in general with the modern Superhawk. The RC51 was completely new V-twin racing platform that won the World Superbike championship its first year racing with the Colin Edwards and Castrol team.

Long jump athletic game
The long jump (previously called as broad jump) is an athletic (track and field) event or game in which athletes attempt to land as far from their take-off points as possible.
The Competitors sprint down a runway (at elite level, generally coated with the same rubberized surface as running tracks), jump to the extent that they can off a somewhat raised wooden board into a pit filled with fine gravel or sand. The minimum distance from the board to the indentation made by the participant in the gravel is measured. If the participant starts his leap with any part of his foot facing the board the jump is affirmed illegal and no distance is recorded.
The correct format of the competition differs, but normally each competitor will get a number of attempts to make his or her longest jump, and simply the longest legal jump counts towards the results. The participant with the longest legal jump at the end of competition is confirmed or declared as the winner. The Speed in the run-up and a high leap off the board are the fundamentals of achievement at the discipline, and it is unsurprising that many sprinters, especially including Carl Lewis, as well compete successfully in the long jump.
