What's New in 1.1?

Java Native Interface

Native methods-methods used by a Java program but written in a different language-have been in the JDK since the beginning. As promised, the native methods interface from 1.0 has been completely rewritten and formalized. This interface is now named the Java Native Interface, or JNI for short.

Where to Find Documentation

• The new 1.1 native methods interface is documented in Using the JNI to Integrate Native Code and Java Programs.

• If you're interested in the pre-1.1 API, you can read Integrating Native Methods into Java Programs. Both trails have many code examples.

• JNI Enhancements discusses plans for the JNI for the next major release of the JDK.
