The following player, seems to be missing out a 'Player' and has a few typos.
This brings about a couple of questions, which are not related to this player, but I wonder anyway..
1. Do changes in the API seem "smooth" or do they commonly require a lot of refactoring?
What are the main reasons for refactoring (i.e. fine-tuning and performance, cosmetic factors, major issues)?
2. Assuming you are a seasoned
Java Developer, what is your learning experience from Java 1.4 to Java 1.6?
What problems does Java excel at?
3. Is it technically feasible to upgrade code from Java 1.4 to the latest versions? Why? Why not?
What is your perceived advantage of keeping up-to-date with the latest code releases?
Do you find that you have to write your own custom libraries? How often? In which (business) cases?
4. Without hoping not to insult anyone's preference, do you consider it possible to have an implementation that is a hybrid of Java and other languages, such as Java and C++, or Java and .NET? How "good" is it?
5. What are your comments about legacy systems developed in Java 1.4 or perhaps earlier. Do they still "work"? Are there a lot of them?
Do business make it a priority to update the code?
