   Feb 15, 2012 · The file name depends on the operating system: on Windows this code would look for ttyutil.dll, on Linux and Solaris libttyutil.so. The next step is compiling the Java code and generating the C header file: $ javac ex/TTYUtil.java. $ javah ex.TTYUtil. The javah tool will create a C header file called ex_TTYUtil.h.

   Step 3: Create the .h File In this step, you use the javah utility program to generate a C header file (a .h file) from the HelloWorld Java class. The header file defines a structure that represents the HelloWorld class on the C side, and provides a C function definition for the implementation of the native method displayHelloWorld() defined in that class.

   How do I create a header file in Java?

   • By default, javah places the new .h file in the same directory as the .class file. You can tell javah to place the header files in a different directory with the -d option. The name of the header file is the Java class name with a .h appended to the end of it. For example, the command shown above will generate a file named HelloWorld.h.
