Answer / srinivas battula

Java is Pure OOPS... Try writing a java program without
Class. i.e. public class Test {}, In this way it satisfies
Oops Concept.
Abstraction: Take any thing like static, system,etc. we
don't know the internal functionalities, but by calling
them we are achieving the task. Here it is hiding the
complexities but representing essential features.
Encapsulation: By writing a program you are grouping all
the methods, variables,etc there by satisfying Encapsulation
Inheritence: When reusability occurs, you satisfy this
concept.
Polymorphism: We achieve it through Overloading and
Overriding in Java in most of the concepts.

Answer / sree

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.

Answer / dhawal

1]here we use static main method means single copy of that
method is created in memory for that particular class means
we can not accept main method out side the class we can call
this method by using class name,ie javac a.java means this is
ENCAPSULATION
2]here println is a method, its defination writen in out
that is output straem means we obtain
INHERITANCE
3]polymorphisum means one name many form basically base
class pointer in our example when u pass String args[] to
main but can manipulate all type of data inside main this is
POLYMORPHISUM
