This provides modular approach to programming. Classes. A class is a concept used in object oriented programming languages such as C++, PHP, and JAVA etc. Apart from holding data, a class is also used to hold functions. An object is an instant of a class. In case of variables, the type is the class whereas the variable is the object.
Static Methods: Methods in are class are generally of two types, * non static methods. * static methods. Non static methods operate on instance variables. Static methods are used to access static variables and their behavior is similar to that of static variables.
