Gir in the Saurashtra region of Gujarat falls in the Gujarat-Rajwara province of the Semi-Arid zone, a belt of thorn and dry deciduous forest between the desert and the Deccan, which also holds Ranthambore, Sariska and the blackbuck grasslands of Velavadar.

The Islands zone, made up of the Andaman and Nicobar group and Lakshadweep, accounts for only about 0.03 per cent of the area of India, the smallest share of any zone, yet it holds coral reefs and species found nowhere else, such as the Narcondam hornbill and the Nicobar megapode…

The Indian Desert zone has two parts, the sandy Thar of Rajasthan and the salt wastes of Kachchh in Gujarat, and the Indian wild ass or khur survives only in the Little Rann of Kachchh, protected in the Wild Ass Sanctuary.

Dachigam National Park near Srinagar, in the Himalaya biogeographic zone, is the last stronghold of the hangul, the Kashmir stag, which is the only surviving race of the red deer group in the Indian subcontinent and the state animal of Jammu and Kashmir.

The Western Ghats zone includes the hill chain and the Malabar coastal plain, and its wet evergreen forests and high shola grassland mosaic hold a very high share of endemic species, among them the lion-tailed macaque of the rainforest canopy and the Nilgiri tahr of the Eravikulam grasslands.

The sundari is a mangrove tree of the tidal deltaic forests of the Coasts biogeographic zone, and the Sundarbans of the Ganga-Brahmaputra delta take their name from it; its wood is hard and durable, and like other mangroves it has salt tolerant roots and breathing roots in the waterlogged mud.

The Trans-Himalaya is the belt lying beyond the Great Himalaya in Ladakh, Lahaul-Spiti and northern Sikkim; it is a cold desert because it stands in the rain shadow of the high ranges, and it is the one Indian zone whose fauna, such as the kiang, wild yak and black-necked crane…

Nokrek lies in the Garo Hills of Meghalaya and represents the North-East India biogeographic zone in the network of biosphere reserves; it is known for the wild citrus relative called the Indian wild orange and for the hoolock gibbon.

The Deccan Peninsula zone covers about forty-two per cent of the country, roughly two-fifths, stretching over the central highlands, Chota Nagpur, the eastern highlands and the Deccan plateau, and it carries most of India sal and teak forests and tiger reserves.

W. A. Rodgers and H. S. Panwar of the Wildlife Institute of India proposed the ten-zone biogeographic classification in 1988 while planning a representative wildlife protected area network for the country, and the ten zones with their biotic provinces are still the official framework.

Private is the most restricted access specifier and is also the default for a C++ class, so private data members can be read or changed only by the member functions of that class, and by a friend function or friend class if one is declared.

Java deliberately leaves out multiple inheritance of classes to avoid the ambiguity that arises when two base classes supply a member of the same name, the problem often called the diamond problem, and it provides interfaces so that a class can still take behaviour from more than one source.

A constructor carries the same name as its class, is called automatically the moment an object is created and is normally used to give the data members their initial values; it returns no value at all, not even void, and it can be overloaded.

Inheritance lets a derived, child or sub class take the members of a base, parent or super class and add its own, which is the main route to code reuse in object-oriented programming; its forms are single, multiple, multilevel, hierarchical and hybrid.

A class only describes the data members and member functions that its objects will have, while an object is created from the class, occupies memory and holds actual values; one class may have any number of objects.

Overloading means defining several functions of the same name in the same class with different numbers or types of parameters, so the compiler decides which one to call; because the decision is taken before the program runs, it is called compile-time or static polymorphism.

James Gosling and his team at Sun Microsystems developed Java, which was first called Oak and was released under the name Java in 1995; its programs are compiled to bytecode and run on the Java Virtual Machine, which makes them platform independent.

Bjarne Stroustrup developed the language at Bell Laboratories, starting it as C with Classes and giving it the name C++ in 1983; it adds classes, inheritance and polymorphism to C while keeping C procedural power, which is why it is called a hybrid language.

Abstraction presents only what the user needs, such as the accelerator and brake of a car, and keeps the internal working out of sight; in C++ it is obtained through abstract classes with pure virtual functions and in Java through interfaces and abstract classes.

Encapsulation means binding the data members and the member functions that act on them inside one unit, the class, and keeping the data private so that it can be reached only through the methods provided; the standard illustration is a capsule holding the medicine inside it.
