J is for JAVA
Archiver
Posts: 46,084
Hello group!
It seems that JAVA is popping up quite often in this group (namely,
with the J-Stamp and TINI devices). It seems now would be a good time
to learn it (it should leave enough time before the J-Stamp is
released...).
For years I've been intimidated by JAVA (and C for that matter)
because of its "crypticness". My brother (a EE/CS major) claims that
JAVA is quite easy to learn. However, he got the brains (I got the
looks), and I'm not sure I believe that statement 100%. Is JAVA
relatively easy to pick up? Specifically, what books or learning
aides could be recommended? Will Parallax come up with some JAVA
tutorials for their Stampinclass program?
Any direction or information would be greatly appreciated!

(C++,smalltalk, etc.). Otherwise, it can be a substantial paradigm-shift.

are just a handful of statements (if, switch, for, etc.). The complexity is
in the library.
Sun is offering a free set of CDs (4 CDs I think) with Java and 6 online
books, and more at
http://developer.java.sun.com/developer/surveys/restricted/java_jumpstart.ht
ml
This is the "Java JumpStart" CD set.
You have to sign up for developer connection, but that's free. It looks like
a great deal for free.

You can think of a Java system as being divided into three parts. There are
the tools (the java compiler), the virtual machine, and the runtime
environment (which includes the libraries or APIs).
With a java-native chip the only part of the equation that changes is the
virtual machine. The tools and the runtime environment stay the same, so you
still have exactly the same libraries. From the programmer's perspective the
learning curve is the same regardless of how the virtual machine is
implemented. The availability of standard libraries is one of the largest
benefits of Java because using library code allows programmers to get their
work done faster and more reliably (the assumption being that libraries are
well tested since they are used by many people).

Chris.

its own set of APIs. (Will the J-STAMP have it's own set API and/or
object oriented?) Personally, I find Object Oriented programming with
JAVA to be quite interesting. Many of the I/O functions for TINI
(LCD, I2C and others) are predefined (similar to the LCD and I2C
commands with the BS2P). You simply have to give the method the
correct data and address and away you go.
