Question { 6431 }

we know that every java prog must follows OOPS Principles.
Anybody can answer, HOW THE FOLLOWING PROGRAM FOLLOWS OOPS
CONCEPTS i.e, Inheritance,Polymarphism,Encapsulation?
class a{
public static void main(String args[]){
System.out.println("Hello World");
}
}

Answer

Inheritance: Every class is extended of Object class, so in
here a extends Object. this is Inheritance.

Polymorphism: means single entity multiple views.
here only one method is there. if here multiple views, then
only it would become like Polymorphism concept.

Encapsulation: Wrapping up of data and code means methods,
variables, code, and all. every java program is based on
Encapsulation concept.
