Question: What are the principle concepts of OOPS?
Answer: There are four principle concepts upon which object oriented
 design and programming rest. They are:/>Abstraction Polymorphism Inheritance />Encapsulation (i.e. easily remembered as A-PIE). 
Question: What is Abstraction?
Answer: Abstraction refers to the act of representing essential feat
ures without including the backgrounddetails or explanations./>
                        
Question: What is Encapsulation?



Answer: Encapsulation is a technique used for hiding the properties&
nbsp;and behaviors of an object and allowing/>outside access only as appropriate. It prevents other obje
cts from directly altering or accessing/>the properties or methods of the encapsulated object./>
Question: What is the difference between abstraction and encapsulation?
Answer: 1.) Abstraction focuses on the outside view of an objec
t (i.e. the interface) Encapsulation/>(information hiding) prevents clients from seeing itís inside&n
bsp;view, where the behavior of the/>abstraction is implemented. />2.) Abstraction solves the problem in the design side 
;while Encapsulation is the Implementation. />Encapsulation is the deliverables of Abstraction. />3.) Encapsulation barely talks about grouping up your abst
raction to suit the developer needs.
