Mathematics with Java: Software Installation
Mt Lebanon HS 2004-5
There are many different flavors of Java, and we will be using exactly one of
them, so read these instructions very carefully! In particular, we
will be using Java J2SE 1.4.2 SDK. This is a huge software
package, of which we'll use a tiny fraction, but you must install the whole
thing (oh well). Also, as with all the software we use in this class, it
is entirely free, so you may legally install the software anywhere you
To install Java, do the following:
- Go to the official download page for J2SE 1.4.2 SDK:
- Find the link, about halfway down, that reads "Download J2SE SDK".
Be sure it reads exactly that, as there are numerous other downloads
on this page that you do not want! When you are sure, click on that
- Read the license agreement and, if you are so inclined, accept the terms
(click on the Accept button, then the Continue button). If you decline
the terms, you will not be able to install Java, in which case you should
- Click on "Windows Offline Installation, Multi-language
(j2sdk-1_4_2_06-windows-i586-p.exe, 51.59 MB)". This is a 51+ megabyte
file, which will take a long time do download (if you have DSL or cable,
that is; if you have a phone modem, it may well take forever, in which case
you should contact me to obtain a CD with this download on it.
Download this file to your desktop.
- Once it has downloaded, double-click on the file
j2sdk-1_4_2_06-windows-i586-p.exe on your desktop to install Java.
Accept all of the defaults -- do not change anything!
- After running the installation process, reboot your computer, and
Java should be properly installed.
There are also multiple versions of JCreator. We will be using an
older, free version, so that we are consistent with the version in the computer
lab at school. In particular, we will be using JCreator LE v2.50
Freeware. To install JCreator, do the following:
- First, if you have not done so already, install Java (see instructions
- Do not go to the official download page for JCreator (this
requires you to enter your name and email, which is not appropriate for high
school students). Instead, download the installer from here, and save
it to your desktop:
- Once it has downloaded, double-click on the file setup-jcreator-2_50.exe
on your desktop to install JCreator. As with Java, accept all of the
- At this point, JCreator and Java should both be installed properly.
To test your installation, try the following:
a) Download the following file to your desktop:
b) Run JCreator
c) Open the file "ItWorked.java" (use File/Open, or its
d) Compile the file (use Build/Compile File, or its equivalent, alt-b
e) Execute the file (use Build/Execute File, or its equivalent, alt-b
f) Read the message that confirms that everything works.
g) If you do not get the message, send me email with as much
information as possible about what happened (include any error messages you
may have received, verbatim, and any other information you might be able to
