OOPS-"INHERITANCE"
- 2. What is Inheritance? • The method by which we can derive a new class from an old called as INHERITANCE or DERIVATION. • The old class referred as BASE CLASS and the new generated class is called as DERIVED CLASS or SUBCLASS.
- 3. Advantages • Reusability • Reliability • Save time and memory • Enhancement • Classification • Industry used
- 4. Disadvantage • Member of the base class becomes private member of derived class but cannot be accessed by parts of your program that are not members of either the base of derived class even though base class is inherited as private by derived one.
- 7. 1.Single Inheritance • The single inheritance is having only one base class and only one derived class. • The single child Inherits the property from single parent class is nothing but SINGLE INHERITANCE. • The child classes use some or all properties from parent class.
- 8. 2.Multiple Inheritance The new derived class can adapt Various properties from various Base classes so that the class is Very powerful. The derived child class is the Combination of various base class.
- 9. 3.Multilevel Inheritance • Suppose one class is derived from its parent class & same class acts as base of another class. That class is called as INTERMEDIATE BASE CLASS.
- 10. 4.Hierarchical Inheritance • The dictionary meaning of hierarchy is as, system of grades of status or authority ranked one above the other. • The classification of objects into various sections. Those sections are nothing but classesdifferent classes.
- 11. 5.Hybrid Inheritance • Sometimes when more than one type of Inheritance is used in the functionality of program then it is called as HYBRID INHERITANCE.
- 12. 6.Multi-path Inheritance • When multiple, multilevel and hybrid inheritance invoked altogether, then it is known as multi-path inheritance
