Abstraction in addition to Polymorphism are rattling closely related in addition to understanding the divergence betwixt them is non equally tardily equally it looks. Their operating model is too rattling like in addition to based upon the human relationship of raise in addition to youngster classes. In fact, Polymorphism needs the cracking back upwardly of Abstraction to ability itself, without Abstraction you lot cannot leverage the ability of Polymorphism. Let's empathize this yesteryear what Abstraction in addition to Polymorphism render to an object oriented program. Abstraction is a concept to simplify the construction of your code. Abstraction allows you lot to persuasion things inward to a greater extent than full general damage rather than looking them equally they are at the moment, which gives your code flexibility to bargain amongst the changes coming inward future.
For example, if you lot were to pattern a programme to command vehicles e.g. starting, stopping, horn, accelerator, breaks etc, how create you lot create that? would you lot pattern your programme merely to piece of occupation amongst auto or bike or would you lot intend almost unlike kinds of vehicles? This is where Abstraction comes into the picture, it allows you lot intend inward damage of Vehicle rather than thinking inward damage of Car. It provides that generalization much needed for a software to live reusable in addition to customizable.
Now let's empathize what Polymorphism provides you? Abstraction is zilch but creating a unlike degree to direct hold details upwardly to sure enough level. Class amongst a higher bird of Abstraction volition bargain amongst most full general details in addition to classes at the lowest bird of Abstraction volition bargain amongst most specific details.
At the transcend of Abstraction, nosotros direct hold consummate abstract things which don't create anything yesteryear itself but specify contracts almost how things volition work. In Java, interface in addition to abstract degree is used to implement Abstraction, but how things volition work? How create you lot code amongst abstract things? Well, hither Polymorphism helps.
It is the magic which plant at runtime to connect abstract things amongst a concrete implementation. This allows you lot to code amongst abstract degree in addition to interface, which results inward much to a greater extent than flexible in addition to maintainable code in addition to then straight working amongst concrete classes. At runtime, Java identifies which concrete class's object is available in addition to and then it calls the implementation of the abstract method from that class.
1) Abstraction allows a programmer to pattern software improve yesteryear thinking inward full general damage rather than specific term spell Polymorphism allows a programmer to defer choosing the code you lot desire to execute at runtime.
2) Another divergence betwixt Polymorphism in addition to Abstraction is that Abstraction is implemented using abstract degree in addition to interface inward Java spell Polymorphism is supported yesteryear overloading in addition to overriding inward Java.
3) Though overloading is too known equally compile fourth dimension Polymorphism, method overriding is the existent 1 because it allows a code to comport differently at unlike runtime conditions, what is known equally exhibiting polymorphic behavior.
I strongly advise reading Head First object oriented Analysis in addition to design equally good equally Head First Design pattern to empathize the object oriented programming better. Both books volition explicate to you lot how to move the OOP principles in addition to basics inward the correct way.
That's all almost the difference betwixt Abstraction in addition to Polymorphism inward Java. They are non a perpendicular concept, inward fact they are rattling closely related in addition to 1 cannot live on without other. Think what value Abstraction volition render if Polymorphism is non at that topographic point to direct hold wages of Abstraction because it is the Polymorphism which links abstract code to concrete implementation. Similarly, if at that topographic point would live no Abstraction, no raise in addition to youngster classes in addition to then at that topographic point would non live whatsoever polymorphic code.

Difference betwixt Abstraction in addition to Polymorphism inward Java
In the concluding paragraph, I tried to explicate how Abstraction in addition to Polymorphism piece of occupation together to render a flexible in addition to maintainable software but to empathize them improve let's create comparative analysis yesteryear analyzing syntactical in addition to the semantical difference betwixt Polymorphism in addition to Abstraction inward object oriented programming.1) Abstraction allows a programmer to pattern software improve yesteryear thinking inward full general damage rather than specific term spell Polymorphism allows a programmer to defer choosing the code you lot desire to execute at runtime.
2) Another divergence betwixt Polymorphism in addition to Abstraction is that Abstraction is implemented using abstract degree in addition to interface inward Java spell Polymorphism is supported yesteryear overloading in addition to overriding inward Java.
