[saikrishnachimakurthi]

I've watched many of your videos, they are truly amazing and very useful for the people to crack interviews, do you maintain any kind of material to share so that it becomes more helpful!

[manasdeora]

Your videos are really helpful. Can you make an informative video that can tell how much package one can expect if he is a spring-boot developer with all range of experiences.

[shalinijha]

Hi! what is the purpose of making a public set method, dont you break encapsulation by doing so? I think you do. If you agree with me, you should make a pop up banner and correct this. Cheers!

[vishnugovindan]

15:36 In your overriding example, in Videos class, your overridden watchOverloadingVideo(int num) is returning int. Wont this cause a compilation error because return type is not the same as parent class method or a covariant type?

[azharmobeen]

I feel there is a small correction.
at 12:50 if you pass null for overloading example then there will not be any compile time error and it will call string method.

[nitinagrawal]

At 5:44 - Are you sure you achieve encapsulation the way you have told?
At 18:43 - An Abstract class can have constructor also.
At 20:20 - Since Java8, difference of providing the default implementation in Abstract class is no more a difference.
At 21:20 - Map is still not direct part of Collection hierarchy.

[ussharma]

it will throw compile-time error, as ByteProgramming is not of type String.
The content was really helpful and clearly presented, please provide interview Question/Preparations set for Collections, Multithreading.

[neerajrajak]

Very Informative, and concepts cleared so well. Thank you so much

[sreeni]

Inheritance --- small correction its extends keyword not extend

[Ravikumar-gjqw]

bro overloaing is also possbile in different class in industry everyone mistaking this OCJP question tq for this tuturials

[bhimraosudrik]

I tried and found that byte.watchOverloading(null); will not give the compiler error with Java 8. It will call the method of String parameter.
