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.”

Please feel free to share your personal opinion.
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
