METHOD OVERLOADING IN JAVA

Method Overloading in Java





If a class has multiple methods having same name but different in parameters, it is known as Method Overloading.


There are two ways to overload the method in java

  1. By changing number of arguments
  2. By changing the data type

Why Method Overloading is not possible by changing the return type of method only?

In java, method overloading is not possible by changing the return type of the method only because of ambiguity.

class Adder{  

static int add(int a,int b)

{return a+b;}  

static double add(int a,int b)

{return a+b;}  

}  

class Test{  

public static void main(String[] args){  

System.out.println(Adder.add(10,10));//ambiguity  

}}  


Can we overload java main() method?

Yes, by method overloading. You can have any number of main methods in a class by method overloading. But JVM calls main() method which receives string array as arguments only. 



Real life example of method overloading


We can save one contact with different mobile number .

OBJECT ORIENTED CONCEPTS

Image
OOPS CONCEPTS  The popular object-oriented languages are Java, C#,php, Python,c++ etc. The main aim of object-oriented programming is to implement real-world entities.   Java is object oriented programming language. Object oriented programming features- 1) inheritance 2) encapsulation 3) abstraction 4) polymorphism    - run time polymorphism    - compile time polymorphism 5) association 6) composition 7) aggregation. Object Any entity that has state and behavior is known as an object. For example, a chair, pen, table, keyboard, bike, etc. It can be physical or logical. Class Collection of objects is called class. It is a logical entity. A class can also be defined as a blueprint from which you can create an individual object. Class doesn't consume any space.
