# Use the Java Implementation of the API

The Java version of the Filter API provides an interface to the core functionality of the C API. It contains one primary class (`Filter`) that wraps the filter functionality of the C API. It is implemented in the package `com.verity.api.filter` contained in the file `KeyView.jar`. The JAR file is in the directory `install\javaapi`, where `install` is the path name of the Filter installation directory.

For more information on the Java API, see the Javadoc in the directory `install\javaapi\javadoc`, and Sample Programs.
