Transcript

  • 1.  
  • 2.
    • OOPs?
    • Concepts in OOPs?
    • Objects & classes
    • Data abstraction and Encapsulation
    • Inheritance and Its types?
    • Polymorphism and its types?
    • Constructors and Destructors
    • Benefits and application
  • 3.
    • It is an approach that provides a way of modularizing programs by creating partitioned memory area for both data and functions that can be used as templates for creating copies of such modules on demand.
  • 4.
    • Objects and classes
    • Data Abstraction
    • Data Encapsulation
    • Inheritance
    • polymorphism
  • 5.
    • Objects :
    • Run-time entities
    • The data of an object can be accessed only by methods associated with that objects.
    • Classes :
    • User-defined data type.
    • Class basically implements the planning & it is nothing but alternative of structure.
  • 6.
    • Abstraction :
    • It refers to an act of representing essential features without including the background details.
    • Classes use the concept of abstraction
    • Data hiding
    • Encapsulation :
    • It is the most striking features of class
    • It provides interface between object’s data and program
  • 7.
    • It provides the idea of Reusability
    • It is a process by which objects of one class acquire the properties of objects of another class.
    • It has super class and sub classes
  • 8.
    • Single Inheritance
    • Multilevel Inheritance
    • Hierarchical Inheritance
    • Multiple Inheritance
    • Hybrid Inheritance
  • 9.  
  • 10.
    • It is an ability to take more than one form.
    • Behaviour is depends upon the types of data used in the operation.
    • Different internal structures to share the same external interface.
  • 11.  
  • 12.
    • Constructor :
    • It enables an objects to initialize itself when it is created.
    • Do not specify return type.
    • Destructor :
    • Mostly in virtual form.
  • 13.
    • To built secure program by data hiding.
    • Eliminating redundant code and extend use of existing classes.
    • It is easy to partition the work in a project based on objects.
    • To have multiple objects to coexist without any interference .
  • 14.
    • Object-oriented database
    • Real-time systems
    • AI and expert systems
    • Neural networks and parallel programming.
