Item description for Java for RPG Programmers: 3rd edition by Phil Coulthard & George Farr...
As the roles of Java in business and e-business applications continue to grow, all iSeries and AS/400 IT professionals have a choice to make---learn Java or get left behind. Programmers, development managers, and architects who want to stay on the cutting edge of their careers must learn how to use and understand Java. IBM is not abandoning RPG, but more and more Java is finding a role in leading-edge applications. For an RPG programmer, learning Java can be daunting, but with the right help, it's a skill that can be mastered. This completely revised and updated edition offers that help by gently yet comprehensively teaching the Java language and core Java-supplied functionality.

Java for RPG Programmers 2nd edition in perfect condition Nov 13, 2007

very different from RPG Apr 30, 2007
Many readers coming to this might like what is described about java. Very different from RPG. The biggest change is the intrinsic object oriented nature of java. If you use RPG 3, then this will certainly be the most distinctive part of the narrative. RPG 4 programmers will at least be familiar.
There are many neat features about java that you should note. Like the higher level data structures, Vector, HashSet, Hashtable etc. These have been thoroughly debugged, and can save you much time recoding. Another difference is a full widget system. RPG came of age when graphics meant character oriented tables. Speaking of characters, java comes with internationalisation. Whereas RPG shows its heritage from an ascii background.
Unsurprisingly, the book has an extensive section on connecting java to a database. Some readers will perk up at this. You can closely compare functionality with RPG. Here, the latter is probably still stronger. But the java designers at Sun have done a competent job with JDBC.
Should be called RPG for the Java Programmer Nov 18, 2003
If you have RPG III or RPG/400 code or this same code that was converted to RPG IV, then this book gives you little to go on but an education in ILE programming techniques. I think that if you were a C or Java programmer trying to understand RPG IV, this book would probably be very helpful.
My impression is that RPG IV should have been called RPG-C. That would have been closer to what it seems it was intended for, RPG to attract C programmers. I think that if one had their applications designed and written in ILE RPG with service programs and proceedures, etc. then this book would be helpful in learning the java language.
If your programs are designed around RPG III, converted or not to RPG IV, plan on having to learn two languages as you attempt to understand Java.
Good Start for the RPG Programmer Dec 2, 2000
I started with a book called Java 2 from Scratch and did a lot of scratching of my head. I think it'll be a good book for me eventually, but not right now. I needed something better to get my feet wet. A co-worker lent me his copy of Coulthard and Farr's book and I spent an evening with it. Afterwards I went to this site and ordered it.
If you are an RPG programmer (I'm from the ILE RPG IV side) and want to begin learning JAVA, this is the book to start with. It does a good job contrasting RPG with JAVA to as to give a decent reference point. No other book does that and I found it to be most helpful. When I finished the book, I felt a lot better about the language but I need to go further with something else (Ivor Horton's book is probably going to be the something else).
I thought the chapter on the Java Onion was really well done and very informative. The chapter on Threads was completly over my head. I'll return to that topic at some future point. The OO chapter was good but I found Jennifer Hamilton's Object Orientation for the AS/400 Programmer does a better job explaining these concepts. Over all these guys did a real fine job.
By the way, I had the privelege of attending their Java seminar at the Fall Common conference in Baltimore and they really made the seminar enjoyable. You should catch one of there presentations some time. They're a good team and keep your attention. They do a good job.
The one beef I have is they left me hanging on page 418 with the MsgBox class. They say it would be simple to add the line of code to your program to use the class. Maybe I'm being stupid, but it wasn't simple for me. They should have at least shown you how to use it because I still haven't figured it out. Phil or George, are you reading this? Maybe someone can e-mail be and let me know. Aside from that irritation, I really liked the book and would recommmend it to any RPG programmer looking to start learning JAVA. A word of caution, it's not the end all. It's a start but you will defintely need to move to something meatier as a next step.
Explains Java in english but lacks needed self-excercises Aug 9, 2000
This is a pretty good book for RPGIV programmers wanting to migrate to Java. It compares all the functions of Java to RPGIV in a way that is very understanding to non-object-oriented programmers. It's a much better book than the past Java books i've read (which are intended for university students familiar with C++).
What this book does lack however are self-excercises. It's merely a good reference book to learning the basics of Java. The authors do a good job of explaining the necessary components. This book also lacks a lot of 'interactive programming' samples other books offer. There were hardly any 'GUI' programming to practice on your home PC...mostly command line tests they show you. It's not a bad book overall.
