Top 8 Java People You Should Know
Here are the top 8 Java people, they’re created frameworks, products, tools or books that contributed to the Java community, and changed the way of coding Java.
P.S The order is based on my personal priority.
8. Tomcat & Ant Founder

James Duncan Davidson, while he was software engineer at Sun Microsystems (1997–2001), created Tomcat Java-based web server, still widely use in most of the Java web projects, and also Ant build tool, which uses XML to describe the build process and its dependencies, which is still the de facto standard for building Java-based Web applications.

7. Test Driven Development & JUnit Founder

Kent Beck, creator of the Extreme Programming and Test Driven Development software development methodologies. Furthermore, he and Erich Gamma created JUnit, a simple testing framework, which turn into the de facto standard for testing Java-based Web applications. The combine of JUnit and Test Driven Development makes a big changed on the way of coding Java, which causes many Java developers are not willing to follow it.

6. Java Collections Framework

Joshua Bloch, led the design and implementation of numerous Java platform features, including JDK 5.0 language enhancements and the award-winning Java Collections Framework. In June 2004 he left Sun and became Chief Java Architect at Google. Furthermore, he won the prestigious Jolt Award from Software Development Magazine for his book, “Effective Java”, which is arguably a must read Java’s book.

5. JBoss Founder

Marc Fleury, who founded JBoss in 2001, an open-source Java application server, arguably the de facto standard for deploying Java-based Web applications. Later he sold the JBoss to RedHat, and joined RedHat to continue support on the JBoss development. On 9 February 2007, he decided to leave Red Hat to pursue other personal interests, such as teaching, research in biology, music and his family.

4. Struts Founder

Craig Mcclanahan, creator of Struts, a popular open source MVC framework for building Java-based web applications, which is arguably that every Java developer know how to code Struts. With the huge success of Struts in early day, it’s widely implemented in every single of the old Java web application project.

1. Father of the Java programming language

James Gosling, generally credited as the inventor of the Java programming language in 1994. He created the original design of Java and implemented its original compiler and virtual machine. For this achievement he was elected to the United States National Academy of Engineering. On April 2, 2010, he left Sun Microsystems which had recently been acquired by the Oracle Corporation. Regarding why he left, Gosling wrote on his blog that “Just about anything I could say that would be accurate and honest would do more harm than good.”

Thanks for showing java god’s
hey “Jenkins Continuous Integration”, plz correct your sentence.
we say JAVA MAN’S

Thanks for compiling the info. Its really awesome.
Thanks a lot for keeping very useful information….
I thought this article of Rod Johnson was very interesting in that it covered the entrepreneurial side of his work…
http://www.sramanamitra.com/2009/01/14/springsource-ceo-rod-johnson-part-1/
Mkyong,
Its all very nice collection of tutorial, Thanks for sharing the valuable information.
Thanks $author! You share some great -2 tactics, thanks for sharing all this and making itclear,enough for any one to be able to get! I’ve subscribed to your rss feed to keep up to date,looking forward to your new post!
thanx for sharing….
Mostly close to what all we think except Hibernate’s Gavin King. No doubt he is very good developer but wasted not only his time but other people time by inventing and then maintaining Hibernate for such long time. There is nothing wrong in inventing wrong thing. Failure is part of game. But what is important is that not realizing that we haven’t found the perfect solution yet!
If he would have invested his time in inventing something simple he would have crossed stature of Rod Johnson or Joshua Bloch. Hibernate and few other softwares (including EJB, JPA where Gavin has given his input as well) are curse but people still haven’t realized it yet. EJB 2.0 would have given the same pain if Rod didn’t have invented Spring. I guarantee you that if Spring would not have been there they (Sun guyz) would not have taken effort to create EJB 3.0. We all would be using same old EJB 2.0 and same ugly entity beans.
The same invention is yet to happen in ORM world and that’s why people still use Hibernate. One great guy and one new invention and then everything changes in few months. Then they realize what shithead they were to use such ugly technology for such long time.
I really like Ken’s comment, I wonder why do you think these frameworks are not good? I am a new java programmer. Should I avoid learning these frameworks? What are the alternatives?
Kevin.
Thanks for sharing. I love java ….. I love them.
Java Concurrency will allow java to rule the server side …
Also it is a structural approach to concurrency
So I think Doug Lea could at least be mentioned like the Collection framework conceptor :)
My 2cts
I think Joshua Bloch should be at #2,…By the way really good article
P.S The order is based on my personal priority.
2 guys here that real creators of java, rest of them just creator some frameworks or tools
that two guys:
James Gosling
Joshua Bloch
I think rest of them can not come near to them.
please check your grammar before you post.

8 wonders of java world
All of these all of them are of top Java people. But there are only 3 legends:
1- James Gosling.
2- Neal Gafter
3-Joshua Bloch
Joshua Blosh also has a wonder book called ‘Java Puzzleres’: http://www.amazon.com/Java-Puzzlers-Traps-Pitfalls-Corner/dp/032133678X/ref=sr_1_1
Indeed one of the best I found for Java.
It’ll be great if you can say what they are doing right now. For example, where is Mr. Mcclanahan now and what’s he doing?
exactly agree with you
thank you for this information. i hope for java developers this kind of information is published even if in future also.
Thank you

It really good to know about consummates of java&&j2ee.
I strong feel, a great name is missing from the list of great people.
My favorite. Sir Martin Fowler.
It`s good to know now all of them, thanks.
which is the primary thread
Nice to see these great people who contributed the Java what we have today.. Its very motivating to know these people. I am still in the begging stage of learning this great language. Please guide me to be a great Java programmer. And you are also great man and i mean it >>! Thanks
Gavin King is really cool..
One Day my photo will be posted in top-9 list…
surely ill assure….
Look forward it :)
HI Mkyong, thanks for showcasing Gods of Java Programming in a great article.
A different kind of blog post but I like it . glad to know about these greats though I was familiar with most of them its good to get all links together, in my opinion James Gosling should be in 1st rather than 10 if you are talking about java.
Where you saw the #10 people :) ?
Is the order right? IMHO James Duncan Davidson deserves better spot than 8, and certainly before say Gavin or Kent.
Hi everybody,
They are Top 8 Most wanted People in the world,
Pls Find and kill them.
¯\_(?)_/¯
good work friend………………………
I too want to be in this list
Gavin King – CDI !
Also whoever invented maven should be held on the same grounds as whoever invented ant. Avoid these guys in all cases ;)
You are missing two people. One is Doug Lea (who wrote Java Concurrency Package) and a new rising star, kohsuke kawaguchi, Hudson inventor.
Thanks for the Doug Lea, i do not know he wrote the concurrency package. Hudson, a great CI… indeed need to be noted as well, will update the list soon…
You forgot Neal Gafter
ya, he is a great guy as well, “co-designed and implemented the Java language features in releases 1.4 through 5.0″.
Great list BUT :
- ANT is not limited to building WEB applications
- same thing for JUnit which is not limited to WEB applications testing
- “award-winning Java Collections Framework” : are you sure the collection framework won awards ?
- “[Struts is] widely implemented in every single of the old Java web application project” : this is wrong, I know many OLD java web applications which directly use JSP & servlets.
- “James Gosling, generally credited as the inventor of the Java programming language” : “generally credited” ? Does this mean someone else claims to have invented the language ?
Hi, thanks for your suggestion,
Q : Are you sure the collection framework won awards ?
A : I didn’t attend the award ceremony, but it’s widely published in many articles, for example,
http://java.sun.com/developer/Books/effectivejava/
Q : This is wrong, I know many OLD java web applications which directly use JSP & servlets.
Ya, indeed, some ancient projects are pure JSP & servlets, but the Struts is still the most implemented framework in the world.
Q : Does this mean someone else claims to have invented the language ?
A : At least the statement is widely acceptable in the world wide.
Sometime, we have to accept the perfect imperfection.
I will benext one in the list
Really !. All the best. Hurray
#2 Martin Fowler
Eric Evans

mkyong,
Nice article. Thanks for providing this kind of valueble info…
