Lesson: The Platform Environment
An application runs in a
platform environment, defined by the
underlying operating system, the Java virtual machine, the class
libraries, and various configuration data supplied when the
application is launched. This lesson describes some of the APIs an
application uses to examine and configure its platform environment.
The lesson consists of three sections:
- Configuration Utilities describes APIs
used to access configuration data supplied when the application is
deployed, or by the application's user.
- System Utilities describes
miscellaneous APIs defined in the
System and
Runtime classes.
- PATH and CLASSPATH describes
environment variables used to configure JDK development tools and
other applications.
