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. And as promised, the native methods interface from 1.0.2 has been completely rewritten and formalized. This interface is now named the Java Native Interface--or the JNI for short.

Where to Find Documentation

• The new 1.1 native methods interface is documented in Integrating 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.

• Or, if you prefer specs, you can read the Java Native Interface Specification.
