Looking for another Green Horn in Seattle/Tacoma Area

I am an old goat that has decided to join the Cattle Drive and learn some new tricks. I was wondering if any green horn (new to java) would be interested in studying together maybe 2 to 4 times a month (beer and pizza helps.) I have some programming background and currently work in an IT shop. Home is in Federal Way and Work is near Beacon Hill just south of Seattle.

Welcome to the Cattle Drive Herbert, you old goat you!

Hope you find some study partners up thar in the Northwest. In between meetings there's always this dusty old saloon place, even if our sarsparilla can't match up to real live pizza and beer. The door's always open!

Enjoy

I live between Columbia City and Beacon Hill - must be near your job. I am entirely new to Java, and even to OOP, though, so I can't offer much. I do eat pizza and drink beer though.

Hi Adam, I do not feel confortable giving to much personal info here so the best way is to Call the VA Medical Center in Seattle, listed in the white pages under US Government, and ask for me in IRM. If you get my answering machine leave a message with your number and when it is best to call. I am off every other monday and 4/10 I am off. I will check my voice mail over the weekend. I have already printed out the lessons and just starting chapter 4 in the book. I do know how to get the environment set up and have played around a little with Eclipse, however, I plan to use a product call TextPad initially (a super version of Notepad.) Don't worry about how green you are. I just wanted someone that was about my speed so we could learn together.

Ha Adam, are you interested in pizza? If so and you are willing to talk about Hashtables, Hashsets, and Hashmaps I'll buy. I am having trouble figuring out where they fit in. If so where is the best place to meet?

I like TextPad. I've used it for years. I still use it for short programs like most of these assignments.

HashMap has pretty much replaced Hashtable. It's very similar but is much faster because it doesn't have (usually unnecessary) synchronization built in. A HashSet is different because it is a Set. It doesn't have keys and values like a hashtable. There is only one of each element, no duplicates, because it is a Set.

Thanks Marilyn. Can you recommend a book or website that has some examples I can play with? I have been writting programs for almost a decade now and never used a hash whatever. I use the backend database calls to optimize my stuff. Also, not sure when I would use a set.

thanks, herb

Glance at the OOP assignments for examples of when you could use a HashMap. Both OOP2 and OOP4 use HashMaps. No need for a database to handle a small app like this. Using memory is good enough.

OOP3 uses an ArrayList where a HashSet could just as easily have been required if we had wanted to rule out name duplicates.

I rarely find need for a Set. I could be wrong, but in my opinion you really only need it to avoid duplicates in your collection.
