What do you mean by Java platform?

The Java platform was urbanized at Sun in the early 1990s with the objective of permitting programs to function apart from of the device they were used on, sparking the slogan "Write once, run anywhere" (WORA). While this intention has not been completely achieved (prompting the riposte "Write once, debug everywhere"), Java is regarded as being mainly hardware- and operating system-independent.

Java was primarily promoted as a platform for client-side applets running within web browsers. This positioning was never very booming. While browser-based applications have had substantial success in displacing standalone applications on the desktop, in 2006 they were not time and again implemented as Java applets. The platform has been more doing well on the server side of the Internet.

The platform contains three major parts, the Java programming language, the Java Virtual Machine (JVM), and numerous Java Application Programming Interfaces (APIs). The design of the Java platform is managed by the vendor and user community throughout the Java Community Process (JCP).

Constructors in C++

A constructor in c++ programming language is a function that initializes the members of an object. A constructor only knows how to construct an object of its own class.
Constructors are not automatically inherited between base and the derived classes. If you don't give one in the derived class, a default will be supplied but this may not do what you want.

If we don’t use constructor then a default one is created by the compiler not including any parameters. There must always be a constructor, though it is the default and empty. If you provide a constructor with parameters then a default will not be created.

Some points about constructors to remember

1. Constructors are just functions with the same name as the class.
2. Constructors are intended to initialize the members of the class when an instance or the object of that class is created.
3. Constructors are not called directly (except for through initializer lists)
4. Constructors will not be virtual.
5. Multiple constructors for the similar class can be defined. They must have different parameters to differentiate them.

What are the Differences between the touring cars and sports cars?

For the careless viewer, there can be a great deal of confusion when it comes to classifying closed-wheel racing cars as the 'touring cars' or the 'sports cars' (as well known as GT cars). In fact, there is often extraordinarily little technical difference between the two classifications, and nomenclature is often a matter of tradition.

Generally, on the other hand, touring cars are based upon 4-door 'family' sedans or, more rarely, 2-door coupe cars, while GT racing cars are based upon more striking vehicles, like Ferrari's or Lamborghini's. Underneath the bodywork, a Touring Car is sometimes more directly associated to its road-going origins, using numerous original components and mountings, while a top-flight GT car is often a purpose-built tube-frame racing chassis underneath a decorative body shell. Numerous Touring Car series, like the BTCC and the now-defunct JTCC differentiate themselves from sports-car racing by featuring front-wheel drive cars with less important engines.

On the other hand, while generally Touring Cars have a lower technical level than sports cars; there are famous exceptions to the rule. The Deutsche Tourenwagen Masters (DTM) is believed to be one of the most technologically highly developed racing series in the world, with cars that, underneath their four-door shells, are more purebred racing machines than the majority FIA-GT vehicles.

What is Road running race game?

The Road running or road racing is the sport of running on a measured course larger than an established road (as opposite to track and the cross country running). Such a race or competition is called a road race. The Road racing provides competitors a variety of challenges to triumph over such as hills, sharp bends, varied roadway, inclement weather, and a large group to try to win against- or with. The Aerobic fitness, or the ability of the body to make use of oxygen, is essential to have to complete the long distances. The Anaerobic fitness, that is, the body's capacity at responding when there isn't sufficient oxygen for the muscle, is essential to charge up hills and past competitors on the finish line. The Road running is unique along with athletic events for the reasons that in many cases first time amateurs are welcome to take part in the same happening as members of running clubs and even in the existing world-class champions.
