This article explains how to develop and implement trees in the Standard Widget Toolkit. Learn how an SWT tree is created and populated with data, how columns can be used to categorize data, how a tree can be extended to support row sorting, and how the tree's content can be searched.

This is complete BS. So Java programmers dont know whats underneath? Come on, the Java API is know by most programmers. Ever thought of Certifications? I'm a Sun Certified Programmer and Web Component Developer. Dont tell me I dont know when I need a HashMap or a TreeMap. I've got a Bachelor degree in Software Engineering, but I also do my certifications so what are you talking about? Also 10 years of experience helps to develop yourself as a programmer.
It would be helpful if you were to respond to something that I actually wrote.
The fact that I condemn using Java in an educational setting as a means to avoid the difficulties of teaching low level concepts does not in any way imply that I think all Java programmers are incompetent.
More specifically, if you can look at a piece of Java code and understand what's going on underneath, then I wasn't talking about you.

Right. The higher level abstractions provided by languages like Java and C# are useful, but you still need an understanding of what's going on underneath. Otherwise, how do you choose between structures like HashMap and TreeMap or ArrayList and LinkedList?
Except that today, the "disease" is carried by Java, and it's even worse because the whole thing has been institutionalized by the educational system. I don't blame Java itself-- it's a perfectly fine language if that's your cup of tea, but it is the current tool being used to train an army of programmers who are completely unable to see behind the abstraction.
The only problem with this is that a Computer Science degree has become completely irrelevant as an indicator of someone's level of knowledge in the subject. Not that it was ever perfect, but it did, at one point, suggest some minimal training and understanding of the basic concepts. "
