The Java 2 SDK is intended for use on Windows 95, Windows 98, Windows NT 4.0 or Windows 2000 operating systems running on Intel hardware, with the following additional requirements and recommendations:A Pentium 166MHz or faster processor. At least 32 megabytes of physical RAM is required to run GUI applications. Forty-eight megabytes 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 65 megabytes of free disk space before attempting to install the Java 2 SDK software. If you also install the separate documentation download bundle, you need an additional 120 megabytes of free disk space.
See the Java Software web site for the list of known compatibility issues. Every effort has been made to support programs written for previous version of the Java platform. Although some incompatible changes were necessary, most software should migrate to current version with no reprogramming. Any failure to do so is considered a bug, except for a small number of cases where compatibility was deliberately broken, as described on our compatibility page. Some compatibility-breaking changes were required to close potential security holes or to fix implementation or design bugs.
The download bundle for the Java 2 SDK includes a copy of the Java 2 Runtime Environment and Java Plug-in. The Java 2 Runtime Environment and Java Plug-in are also available as a separately downloadable product.
