Inheritance

 Inheritance



What is the meaning of Inheritance ?

  • Simply,inheritance is owning or belonging something/s from one person/generation to another person/generation.It may be anything.
What is Inheritance in JAVA ?

  • Taking the things/properties in one JAVA class to another JAVA class is called as Inheritance.
What are two categories of Inheritance Concept ?
  • sub class (child) - the class that inherits from the initial class.
  • super class (parent) - the class that is used to inherit other classes.
How do we inherit one class from another class ?
  • First of all we should create a relationship between 2 classes.
  • For that,we use the keyword  extends.
  • If we consider the process of manufacturing a new car as an example,that car may contain newest features and it will include the  features of its previous version.
  • So, the oldest version can be identified as the super class and the modern version will be the sub class.
  • The older version has a colour,name,lights,..etc.Actually they're variables.And it perform common tasks like drive,reverse,break,..etc.They're methods.
  • Modern car will contain all those features as before and it may have modern features like cameras,gps,wifi,autopilot,...etc
  • So we can inherit those things like below.

class Oldcar{

String color;

String name;

  void drive(){

   }

  void break(){

   }

}

class Newcar extends Oldcar{

String camera;

string wifi;

  void autopilot(){

   }

}


So this is a simple description about Inheritance.

Let us meet with another new article soon !

Variable and Method types in JAVA

Image
  Variable types..... 1) Local variables/method local they are inside a method. eg :- class A {         void a () {         String x ;         }           } 2) Instance variables the variables inside a class. but cannot be inside a method. eg :- class B {          String x ;         } 3) Static variables/class variables Static variables must be in a class. but it cannot be inside a method. eg :- class A {          static String x ;         }            Method types..... 1) Pre - defined methods. - pre built methods in JDK - public static  void main (String[]args) {} - print (); - get (); - set (); 2) User - defined methods. - methods created by the user. -2 types static methods - static void draw () {} non static nethods - void eat () {} / void write () {}   ...

Polymorphism

 Polymorphism The process of calling the sub class methods by using the super class reference with the help of Overriding,Inheritance and Casting concepts. After we override a method of a super class inside a subclass,we can do casting and then through the super class reference,we can call the sub class method. We can perform many tasks in different classes by using this concept. This simply means "Many Forms". Assume that there is a company.It stores Biscuits and Cakes seperately.For that we have to develop a system to store them in the correct manner. As Java is a compiler,it executes its codes line by line. Now if we have either cakes or biscuits,the should have to store in their correct places. So for that we can use polymorphism with casting,inheritance and method overriding concepts. We can create seperate objects for those sub classes. Super class is called and then the sub class is executed. This is a simple idea about how we can use polymorphism practically. Let us d...

Casting

Image
Casting Integer Hierarchy long int short char byte Floating Hierarchy   double float According to the above sequence the data types that are in the highest point have the highest power than lowers. Upcasting We can understand upcasting simply as giving the subclass object to the super class variable. In upcasting we cannot access higher types by lower types. But lower types can be accessed by higher types. Downcasting Converting the sub class object added to the super class variable back into sub class variable. This is simply giving the super class variable to the sub class variable. For this,sub class object is used as parameter.
