Hello Robert, both of them are valid suggestions, and one way or another they are also included in this article. For example, the rule which says that "Encapsulate what changes" is exactly to hide your data. I really like your second suggestion because if there is a single rule to follow it must be good names for variable, methods, and classes

I think you are right. My first introduction with Uncle Bob was with Clean Code, that was remarkable but this book is at par of that.

I think you are right. My first introduction with Uncle Bob was with Clean Code, that was remarkable but this book is at par of that.

Yes :-)

Yup, that's a great book and updated version of Java 8 in Action.

You seems to die-hard Scala fan :-)

Do you mean even Effective Java?

yeah, agree, I need to add few more Java 8 questions on this list. thanks for feedback.

Not really, it can be tough for beginners but yes if you have decent Java experience, you should know all the answers.

Not in this era of DevOps. But again, the choice is yours. Tools like Puppet or Chef are good for infra automation and help you to quickly build your evnvironemtn reliably, consistently and easily. .

If you want to learn just one, choose Maven. Even Gradle is better and latest, Maven is still most widely used.

It's a good tool but you can ignore if you are no interested on monitroring and your organization is not investing on that.

Well, my take was that a developer who knows better tools and knows his tools better is a better developer than others. But, yes, that's my take on this quote and that's why I love to learn tools which help in development, testing etc.

That's true but it's not the easiest book out there because topic itself is complex. A course will help you better.

Yes, these are also good resources. Thanks for sharing them here.

Thanks

I think the most important reason is the power of language and how easy it is to learn or do something on it. By power I mean, what can you do using that language without breaking stones and Python is great on that. It offers tons of library for doing virtually anything.

If you need an easier book on Algorithms then try Grokking Algorithms by Aditya Bhargava

Thanks Josh.

Thanks

Not really, if someone has mugged how to reverse a singly linked list, he will fail as soon as you change the problem a little bit e.g. asking to use recursion or iteration or in place or just asking to reverse in pairs. These are good questions because you can do in a few lines if you are a good developer, shows the problem-solving skill of candidate, and also allows the interviewer to increase difficulty level slowly.

Well, you always need a bit of brush up and practice before going into an interview.

Thanks Calvin

Yes, that's again a great book and I could have included in this list but I left it as a general programming best practices book.

Modern Java in Action is the updated version of Manning's Java 8 in Action and contains changes from Java 9 and 10. I, agree on a good book to add to this list, but now that you have mentioned, people can take note of that.

While I agree that Scala and Haskel are very good programming language but they are not for average developers, otherwise it would have grown like Python or JavaScript. There is a reason why Java, Python, and JavaScript is ruling the world, they all are accepted by the mass. That acceptance is very important.

But, In most organization it doesn't work like that, you have to wear many hats at the same time.

Why Serge? I think Java, Python, and JavaScript is the only three language which is going great at the moment.

I think you can use jConsole to check deadlock in realtime.

yes, by using this coding technique you can avoid deadlock.

Hello Gautam, Yes, there are many useful machine learning libraries in Java like Weka and Deeplearning4j but most of the development is happening in Python and R where libraries like TensorFlow, Sci-kit, Keras, and Pandas are very active and popular.

Definitely Log4j2 is faster but still abstracting your logging library by using SLF4j is not a bad option.

Yes, Spock is a good framework but you need to know Groovy, which is also not bad if you can.

not the best, but yes, good books.

Hello Phil, I haven't read that yet but looks a good book to learn JavaFX, thanks for the suggestion.

Thanks, that's a good book.

This is just a blanket comment without any argument. Though I agree, it's opinionated, it makes smart choices and also gives you the tool to customize it.

I second, unit testing/automation/integration testing is the single most important thing for Java developers. There is a lot to learn on that space.

yup, that's bad, but I mean books simply denote it's Book, yes there will be some situation where it's not clear and in that case, as you said, Stream<Book> will make sense.

Hello Kevin, I agree but most of the time name of the variable and type provide same information e.g. Books book = new Book() or Book book = getBook().;

Now that type is gone, the variable name becomes even more important because it has to indicate type as well.

Yup, you are correct. In some cases, though Enum as Singleton is also an easier option.

That's not true.

Thanks Gunnar, that's very useful feedback and pinpoint the problem. I wrote this article keeping new developers and fresh computer science graduate in mind but then again I erred on SVN part. Though, I would be more than interested in what would have been your list, what tools or skills would you have liked to see on software developers?

I have to agree with you on this point, the Cobol example just killed the argument.

Hello Gunnar, Software development is not just about writing code, it's much more than that. You need to get requirements, document them, develop, code, test, support and even educate people. Giving a presentation, creating diagrams to explain your system all are part of Software developer's day to day job. Though I agree that you might not have used PPT, you might have used any other tool e.g. Visio to create diagrams etc. The whole point is to have a tool which lets you do that and PPT is most commonly available.

Well, Confluence is good for documentation, I have hardly seen any software requirement document written over there.

Thanks for that, I know, SVN is dying and Git is going to take over all but in the real world, there are still a lot of projects which use SVN and that's why it's an important tool to learn.

Sorry, Guillermo that you are disappointed, but you clarify what was your expectation when you read the title? I use these tools daily and they are essential for any programmers, I don't really know why so many negative comments.

That's not true, these are excellent tools and I used them daily, don't you use Git or SQL or Linux commands? But, there is something which I missed because it generates same comments all over the internet, not just on Dzone but on Reddit as well. Is that title?

Sorry, but can you clarify. These are the tools I used daily and they are useful, not sure why this article is sparking so many negative comments.

Well, I have mentioned Linux commands but yes they are awesome tools

Not really, if you also write requirement specification as part of your development, you need to know the MS Word. same goes for PPT.

Well, kind of yes, particularly for this example, but we don't always use Arrays.asList(), especially if arguments are not String and Integer.

Thanks, Jim, some nice thoughts there. You also have point with programmer should not start with Android development but I have seen a trend that the Idea of developing apps are bringing many people to programming. but yes, they would do better to follow your advice.

Hello Mark, You may be right but the opportunity Java provides is unparalleled and Kotlin has a long way to catch that. Also learning Java is quite easy, though that's subjective and some people may find Kotlin easier to Java.

Hello Lee, I mean brand new developers that don't know how to code. If you already know Groovy/Grails and doing web development, you can start with kotlin. In fact, your Groovy knowledge will help you to learn Kotlin faster.

Hello Craig, Effective Java 3rd edition should be the first book, I didn't include on the list but I mention it specifically because I think it's must read for all developers.

Thanks Thai, yes doing every toy project in the language you want to learn is a great idea. I am thinking to write a file recon tool in Scala for one of my project, let's see how it goes.

I am almost done with Effective Java 3rd Edition :-) but High-performance in-memory computing with Apache Ignite seems interesting. Thanks for suggesting that.

When you have mutable object e.g. Date, you must return a copy of it instead of original reference. One of the thing people miss while creating an immutable class in Java.

Well, Certifications are globally recognized and definitely provide value in terms of Job and credibility. I am not saying that you definitely need certification to get the job but it adds value. Also, apart from recognition, it boosts your knowledge and makes you expert which indirectly help to do well on interview and day to day job.

Thanks for sharing your experience. Here are my 5 tips to prepare well for Java certification Exam

1. Code Dailly
2. Good Study Book
3. Good Exam Simulators e.g. Whizlabs
4. Forums e.g. CodeRanch
5. Solve Practice Questions e.g. free 1Z0-808 mocks

I think its not that Java doesn't need it , we have seen many example where operator overloading can make code more readable and fits naturally. but in my opinion Why Java doesn't support operator overloading because if you allow programmer to do operator overloading they will come up with multiple meanings for same operator which will make the learning curve of any developer hard and things more confusing and messing. Its been observed that there is increase in programming errors when language supports operator overloading which in turn increase the development and delivery time and since Java and JVM has taken most of developers responsibility in memory management by proving garbage collector it doesn't really make sense to left this feature to pollute the code and a loop hole for programming errors.

How HashMap works in Java

In my opinion its a usecase or scenario which decides what to use obviously if you have just one reader and one writer, synchronized is the best choice because of clean and simple approach while in case of multiple Reader and Single writer , Lock interface can provide much better performance.

Thanks

I must say great post , never know these details about generic. Thank a lot for bringing these to us.

How volatile keyword works in Java with example

>One can also use Void class in Generics to specify that you don't care about the specific type of object being used.

Anyone please Why do some one wants to do this , if type-saftey is not requirement then one can use collection class without generics ?? what do yo say

but this could be a interesting interview questions :)
