Getting the Java Developer's Kit
Getting the Java Developer's Kit (JDK)
-
Okay, OOP is quite abstract and if you're like me,
your brain is probably swimming by now.
-
So let's step back and do some really concrete stuff. let's get ourselves
a copy of the Java Developer's Kit so that we can actually try out some
actual examples of all of this stuff.
-
The JDK is a development
environment which allows you to create Java Programs.
-
It includes such essential things as the java class libraries, the javac
bytecode compiler and the java virtual machine which you can use to execute
your applications.
-
There are plenty of other development environments such as Symantec
Cafe, Microsoft's SDK, J++.
However, I recommend that you go through the process of developing with
the JDK in order to really get a good feel for the processs of creating
and compiling Java by hand. Visual developmnt tools are very nice, but
they do not help you understand the inner workings of the language.
-
The most recent version as of this writing is JDK
1.1.5 and will come as a self extracting archive. Here is a screen
shot of what the Javasoft site should look like. And here is an example
of a Save Dialog generated by my web
browser when I began to download the JDK. Give yourself plenty of time
because the JDK takes a good ten minutes to download, especially over a
modem. Go ahead and download the documentation as well.
-
Once you have downloaded the self-extracting archive, you should execute
it (typically by double clicking on it). When you do so, the install program
will walk you through an installation of the JDK on your local machine.
Here is what it looked like when I
started Install Shield.
-
In order to keep your hard disk organized, I recomend installing the JDK
in a top level folder like "C:\Java\Sun" because it is likely that you
will get other "Java-centric" libraries and development kits in the future.
-
When the installation program is done working, you should have the JDK
installed on your machine. Here
is what my directory structure looked like after I installed it:
