Obtain the JNI function signature from the header file JNIEXPORT void JNICALL Java_HelloWorld_cfunctionģ. * DO NOT EDIT THIS FILE - it is machine generated */ This will generate a file HelloWorld.h which contains : Generate a Header file from the class file

Compile the Java code and generate the class fileģ. Obj.cfunction() //Calling the native functionĢ. System.loadLibrary('forhelloworld') //Linking the native library Native void cfunction() //Declaring the native function Note the modification mentioned in step 4 below. The same can be implemented with C++ too. Passing Integers and Strings from C to Java.Writing a HelloWorld in C and calling it from Java.Therefore the scope of this post is to show you how to implement JNI with simple examples for : I found that most of the online documentation on JNI seems pretty scattered and obsolete. You might want to use a feature not present in the standard Java class library or you might just want to use an existing library written in some other language.

writing applications in Java, there are times when Java alone fails to meet the needs of an application. using Arrays.toString() for printing object array contents
