Thanks for sharing the information Simon

Thanks, Adam & Mike!

Thanks for sharing the information Alex!

Thanks, Yasin!

Thanks, Pouria!

We do not use it in day-to-day code and there but it is used for some of the things under the hood, It is better to know these things.

I agree with you Jhon, There are several approaches to do the same thing!

Thanks, Vaishnavi!

Thanks @Sanat

Thanks @Rahul

Thanks for checking it Mohan, I will update this.

Haha! Does not matter how much they try to deprecate it but it will be always there.

Yes, I agree!

Thanks for sharing it! @Esko

Yeah, I agree! Wrote that statement just to make the distinction.

Thanks @Gayatri

@Suxin Li Sorry for replying late, As mentioned it the article,

We know every Child class inherits variables and methods (state and behavior) from its Parent class. Imagine if Java allows variable overriding and we change the type of a variable from int to Object in the Child class. It will break any method using that variable, and because the child has inherited those methods from the Parent, the compiler will give errors in the Child class.

It not just about what method returns, It is about what variable method is using,

Great details Alan! Thanks for sharing.

Thanks Amit.!

Thanks Amit!

Thanks Divya!

Thanks Ravindra!

Thanks! @Atul

I am facing the same kind of integration problems with scala, gradle and intellij, If I compile the project through gradle it compiles successfully but intellij is not so intelligent to compile it.

Thanks for combining these features in one article, excited to see them.

Thanks for mentioning it @Ravi Hasija

Thanks @Raghavan!

As mentioned in the blog "Because SDKMan is written in bash and only requires curl and zip/unzip to be present on your system. You can install SDKMan on Windows as well either by first installing Cygwin or Git Bash for Windows environment and then installing SDKMan by running mentioned commands."

Hi Andreas! Thanks for mentioning, I was trying to focus on the concept only.

Thanks!

Thanks Miten! Will do that in near future.

Thanks Brian! I appreciate it!

Thanks, Sunit! Thanks for your response!

Thanks Silvia!

Thanks!

Hi Ajitesh, Gcloud provides it for free or it costs?

Nice article Eugen!, I am using streams for 2 years but was not aware of some methods discussed by here.

Nice summary!

mention not.

Good article Justin, I was not aware of most of them. I also wanted to point out that static initializers get called when the class loads into the memory not when the application starts. This will happen if our class is getting loaded into memory during application start.

Thanks Denis!

Thanks, Effie, I can't help without seeing your code, you can complete code for this blog on https://github.com/njnareshjoshi/articles/tree/master/spring-data-jpa-auditing, tell me if this helps.

Yes you can

The link "Adroitlogic Project-X" is broken, can you please share some code or git repo.

Thanks, Anastasiia, Your research about hiring a Java devs is good.

Ohh my god, I think you are not in a good mood today and I know your time is very precious so don't waste your time in posting shit comments on a shit article and do something productive.

7000 more readers have read it and did not found it shit, you found it shit that's your perception, I thank you for telling me your perception.

By the way, I have not posted it on DZone and They have picked it and I am pretty sure they have done this for a good and productive reason.

Thanks a lot, Really nice to hear that at least you have something to say.

Yes, you are right but sometimes based on our requirements we need these kinds of things e.g. I have to do a lookup.

Totally agreed.

Thanks for mentioning, I was totally unaware of it.

Okay, thanks!!!

Good point

Having an opinion is good but forcing it on others is not. However, I accept what you are trying to say that novice programmers might get confused but chances are very less. Because anybody can see the code and can also see that the method is not static.

I don't want to get into a fight here but you are completely wrong here, I am not saying that we should always override it but we should when we are in need.

My whole purpose was to talk about override and overload not equals and hashCode and their contract.

And what are you trying to prove by saying "including the author." , First of all, this not something a professional says and it does not suite to a person who has this much experience. We should be a little bit polite and give respect to others.

And assuming what others don't know because of what you know is not a good idea.

Totally agreed.

Agreed We will not be overriding those methods always as I have not done in the example. But whenever we work on a real time project we should and it is good to implement those methods in your classes specially POJOs.

It is not required but we can use a different return type but must use different argument.

I apologize for your inconvenience but DZone Have picked it up from my blog, I have not posted it.

I am pretty sure that they have done it for some good reason.

Yes We can store all the request info as well e.g. headers, params, url, body etc.

Certainly, Hibernate Envers have an edge over JPA auditing. And actually, this article is the first in the 3 article long auditing series which I am working on next is https://programmingmitra.com/2017/02/automatic-jpa-auditing-persisting-audit-logs-automatically-using-entityListeners.html

And I am going to write the 3rd article which will be about hibernate-envers

This conversation solved my confusion.

Because we want to hide the copy constructor and instead use our defensive copy method for copying.

because we don't want them to be accessible outside of the class, we will call them from our defensive copy method only

Even though we have done that in equal operation and it would have returned true but still we are getting different object after cloning

Thanks for noticing buddy, it was a typo and I have corrected it.

Yes surely, thanks for mentioning

Yes you are right, but aren't dynamic dispatch and polymorphism same things?

Yes surely, copy constructors should be private I forgot this. Thanks

Very nice and explanative article, Thank you!!!!

Yes you are right,Thanks for your answers

Thanks Robert, I will

Java 8 lambdas get converted to invokedynamic, And sorry but I don't have idea how that works

java.lang.Class is actually the internal structure of your class, everytime JVM loads a class into memory it creates an object of java.lang.Class<YourClass> in PermGenSpace.

And As I have mentioned in another comment In the source code of java.lang.Class, you can clearly see that "The primitive Java types (boolean, byte, char, short, int, long, float, and double), and the keyword void are also represented as Class objects."

If you study all the point which I have written in favor of "Why Java is a purely Object Oriented language", you clearly say even if these are primitive for developers, JVM internally treats them as objects.

As I mentioned in a previous comment, primitives are not objects for us, JVM treats them as some kind of internal objects on which we are not allowed to perform any operation as we can on objects.

I agree

Yes, I understood your point and I agree to it but Just try to read the source code of java.lang.Class, you will clearly see that "The primitive Java types (boolean, byte, char, short, int, long, float, and double), and the keyword void are also represented as Class objects."

If you study all the point which I have written in favor of "Why Java is a purely Object Oriented language", you clearly say even if these are primitive for developers, JVM internally treats them as objects

I do agree with your second point that outer classes do behave like static and can be understood as static.

But I don't agree on your first point "it's technically held in the JVMs internal structure for the class and not in j.l.Class."

java.lang.Class is actually the internal structure of your class. Everytime JVM loads a class into memory it creates an object of java.lang.Class<YourClass> in PermGenSpace.

thanks all for giving your precious time and mentioning your points

thanks Michael, i have corrected it.
