Do you want to run Java programs, or do you want to develop Java programs? If you want to run Java programs, but not develop them, download the Java Runtime Environment, or JRE. If you want to develop Java applications, download the Java Development Kit, or JDK. The JDK includes the JRE, so you do not have to download both separately.

We support the following platforms:

• Oracle Solaris Operating System
• Microsoft Windows
• Linux
• Mac

For supported processors and browsers, see Oracle JDK 7 and JRE 7 Supported Systems Configurations.
