System Requirements
The Java 2 SDK is intended for use on
Microsoft Windows 95,
98 (1st or 2nd edition), NT 4.0 with Service Pack 5, ME, 2000 Professional,
2000 Server, 2000 Advanced Server, or XP operating systems
running on Intel hardware.
A Pentium 166MHz or faster processor with at least 32 megabytes
of physical RAM is required to run graphically based applications.
Forty-eight megabytes of RAM is recommended for applets running
within a browser using the Java Plug-in product. Running with less
memory may cause disk swapping which has a severe effect on
performance. Very large programs may require more RAM for adequate
performance.
You should have 70 megabytes of free disk space
before attempting to install the Java 2 SDK
software. If you also want to install the
documentation download bundle, you will need an
additional 120 megabytes of free disk space.
Installation Instructions
In this procedure, you will run the self-installing executable to
unpack and install the Java 2 SDK software bundle.
Note: After the Java 2 SDK software has been installed,
you will be asked to reboot your system, which completes the
registry modifications that you will need if you ever want to deinstall
this product later. To continue using these
instructions after rebooting, either print them now or use your
Web browser's history function to get back to this page.
The installation procedure has the following steps:
- Check the download file size
- Run the Java 2 SDK installer
- Delete the downloaded file(s) (Optional)
- Update the PATH variable
- Check the CLASSPATH variable
- Start using the SDK tools!
- Uninstalling the Java 2 SDK
If you have any difficulties, see the Troubleshooting
section at the end of this document or use this link to report
an installation problem.
Note: For any lines on this page containing the following notation,
you must substitute the appropriate update version number for the notation.
<version number>
For example, if you are downloading the installer for update 1.3.1_01,
the following file name:
j2sdk-1_3_1_<version number>-windows-i586.exe
would become:
j2sdk-1_3_1_01-windows-i586.exe
1.
Check the download file size
Before you download a file, notice that its byte size is provided
on the download page.
Once the download has completed, check that you have downloaded the
full, uncorrupted software file.
2.
Run the Java 2 SDK installer
The file j2sdk-1_3_1_<version number>-windows-i586.exe is the Java 2 SDK installer. If you
downloaded it instead of running it directly from the
web site, double-click on the installer's icon. Then follow the
instructions the installer provides. When done with the installation,
you can delete the download file to recover disk space.
Installed Directory Tree
The Java 2 SDK has the directory structure shown below.
jdk1.3.1_<version number>
