Existing extensive Web system is developed usually using object oriented language.Object-oriented is that a kind of software is opened
Forwarding method is referred in programming using encapsulation, is inherited and the design methods such as polymorphic.Encapsulation refers to and will deposit in real world
The attribute of some object bound together with behavior, and be placed in a logic unit.The logic unit is responsible for institute
The attribute of description stashes, and all access of outer bound pair object built-in attribute can only be realized by the user interface of offer.This
Sample does the protective effect that can not only play to object attribute, but also the maintainability of software systems can be improved.Object is that people want
The anything studied can regard object as from simple integer to complicated aircraft etc., it can not only indicate specific
Things, moreover it is possible to indicate abstract rule, plan or event.Object has state, and an object describes its shape with data value
State.Object there are also operate, for changing the state of object, object and its operation be exactly object behavior.Object implementatio8 data
With the combination of operation, it is packaged in data and operation in the entity of object.Class is the object with identical characteristic and behavior
It is abstract.Therefore, class is the abstract of object, and object is the materialization of class, it may also be said to, object is the example of class.Class is actually
A kind of data type.For example, parrot can be considered as a type, and a specific parrot can be considered as an object.Class has
Attribute, it is the abstract of the state of object, and the attribute of class is described with data structure.Class has operation, it is the behavior of object
It is abstract, with operation name and realize the method for the operation and describe.
Caching refers to the buffer area of data exchange, when a certain hardware will read data, can search from caching first
