Introduction to Inheritance ,[object Object],[object Object]

Inheritance ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Picture about Inheritance C lass B F eatures: a,b,c C lass D F eatures: a,b,d,e,f a b C lass A features: a,b c d e C lass C F eatures: a,b,d,e f

Multiple Inheritance ,[object Object],[object Object],Driver - license - Y ear of approval Conductor - A ccount number Taxi Driver - area House Boat Houseboat

Inheritance and Capsulation ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Basic example ,[object Object],Human string name void sleep() void drink() void eat() Programmer int salary void implementApps() void beNerd()

Overriding? ,[object Object],Human string name void sleep() void drink() void eat() Programmer int salary void implementApps() void beNerd() void drink() void eat()

Abstract Class ,[object Object],[object Object],[object Object],[object Object]

Example <<abstract>> Mammal string name void makesound() {abstract} Elephant int trunkLength makesound()

Example <<abstract>> Figure int x, y double calculateArea() {abstract} Circle double radius double calculateArea() Rect double length, height double calculateArea()
