JNI Tutorial

JNI is a two-way interface that allows Java applications to invoke native code and vice versa. The JNI is designed to handle situations where you need to combine Java applications with native code.

Java native methods are methods declared in your Java code (much like you declare an abstract method), but which are actually implemented in another programming language.

Here is the series of JNI articles where you can learn from basic Hello World program, JNI setup to complex programs.
