Podcast Episode 15 – Collections


In this episode of the How to Program with Java podcast, I will talk in-depth about Collections. Specifically, I will be covering the following topics:

– What is a Collection?
– Which Collection interfaces are most popular?
– What are some of the most common implementations of these interfaces?
– When should you choose one implementation over another?

As always, if you like the show, please give me a rating and a review. If you do I’ll be sure to mention you at the beginning of the next show.

If you have any questions about programming, feel free to email me and I will answer your question on the show! How cool is that?

Take care everyone, and happy learning!

    I absolutely love the podcast and the tutorials. I am still back around episode 14 or 15, so forgive me if you have already incorporated this suggestion in future episodes. In your intro, your voiceover guy says something to the effect, “..you too can becom a Java programmer with absolutly no knowledge of programming.” I think the last clause is a little misplaced. Noone wants to become, or be thought of, as a Java programmer with no knowledge of programming. What you mean is “…you too, with absolutely no knowledge of programming, can become a Java programmer…” The difference is subtle, but the meaning is drastically different. This is pedantic, I know, but for some weirdos like me it is going to be bothersome every episode.
    Thanks for all of your hard work. Keep it up!

      Hey Daniel,

      Thanks for the tidbit of information. I hadn’t even thought of that interpretation of the sentence, you are the first one to bring it up. Obviously the intention I had was to say that you could learn how to program, even starting with no knowledge.

      Unfortunately I haven’t changed it yet, as changing it would go to the tune of $300. So I guess the question is, does it really bother me that much? As of this moment, I don’t have $300 to throw at this issue 🙂 I’m more than willing to accept donations though! haha

      Take care Daniel, and I’m glad that you love the podcast!

    Thanks so much for the podcasts! I have been listening to them in my car for the past week or so. Real good. I plan on buying your e-book (kinda wish you had a print but I understand the cost in that).

    I take a Collections in Java class at a community college. Your info has been the most beneficial than almost anything on the web!

    I just had one question, any material from you about GUIs in Java?? I’ve been looking around your blog and haven’t found anything. Looking for something with Panels, Containers, ActionListeners, etc.

      Thanks for the kind words, I appreciate that very much!

      I did think about putting my book into print, but when I received the quote it would have to be sold some something like $80 to cover costs. I didn’t want to charge that amount for just a book, so I’ve stuck to the eBook route.

      As for the GUI lessons, I’m not a big fan of the Java GUIs in general and prefer to do my programming on the web. This means that I use HTML as my GUI and Java serves as the “back-end” business layer technology.

      I know there are tons of great free tutorials on YouTube that cover Java GUI topics that I’d suggest you check out.
