Java 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.

"Linked list with pointers? is this 19th century or what?

No, but I would expect that anyone graduating with a degree in Computer Science would have some familiarity with the fundamentals of programming, and those would include pointers and basic data structures and algorithms. Unfortunately, this doesn't seem to be the case for a good portion of graduates anymore.

You're right. Take into mind the word "algorithm" - it's much older than the 19th century, but it's essential to understand what is meant by it when you're doing serious programming work. As well as concepts - linked list, stacks, trees, enumerations, arrays, even pointers and memory addresses - that are important, it may be possible that a programmer never has to implement something such basic on his own, but it's neccessary that he understands what's going on "under the hood", so if problems occur (and they usually will), he has a clue about how to solve them. Surely, this is often considered "old-fashioned" or "unmodern" by many novice programmers who know how to click in "Visual BASIC" and consider themselves geniuses. But when you need to optimize code, you're thinking in "old-fashioned" categories like exponential complexity, iteration loops or memory layout.

Furthermore, I agree with your consideration that today's educational concepts in computer science don't seem to put much emphasize on teaching basic concepts. But finally, it's these basics that enable you to understand how things work. But if you're just keen on a BA, MA, Dipl.-Inf. or some other degree that you can show around, while treating your PC as a worse typewriter, it should be sufficient. :-)
