I have a question about question 18. Why par.foo() is "I am foo in super"?. par is a reference object of "parent" class which is pointing to "child" class, right? then par.foo() should give : - I am foo in child ....
Thank you so much for amazing videos. Could you also please make videos on system design interview questions in Java like 1) Design a traffic control system 2) Design a elevator system 3) Design a parking lot system etc.

Thank you so much, edureka! for uploading this video. This is so helpful for interview preparations. All the other videos breaking down the basic concepts of Java were also excellent.
While explaining that Strings are not mutable, why the compiler didn't throw any error when you tried to concatenate it with str.concatenate("hi... ") ???
What we mean by immutable is that you cannot change specific terms in the string. For example, 'Hello' is the string. You cannot change the string to 'Wello' by any case as that is not allowed. Whereas concatenation is allowed because the original string plus some other string is taken. Hope that solves your query.

Hey Anurag, thanks for checking out our tutorial.

Hi Abhra, It's possible to have non abstract methods in abstract class. When you want to prevent instantiation of the superclass. Child classes can use or override the public and protected non-abstract methods defined in the abstract class.
Hey Ridhi, thanks for checking out our tutorial! As a mainframe developer you would some idea about programming. You can learn Java if that's the career track you are interested in. You can check out our Java course that is designed to give you hands-on experience: www.edureka.co/java-j2ee-soa-training. You will also get to work on a project towards the end of the course. The pre-requisites to learn Java are prior programming experience and familiarity with basic concepts such as variables/scopes, flow-control, and functions. Prior exposure to object-oriented programming concepts is not required, but definitely beneficial. Hope this helps. Cheers

In abstract class, how to call non abstract method from child class if abstract class doesn't allow us to create object?
Hi Abhra, It's possible to have non abstract methods in abstract class. When you want to prevent instantiation of the superclass. Child classes can use or override the public and protected non-abstract methods defined in the abstract class.
Sir your explaining way is Awesome.
