Trail: Java Native Interface
Lesson: Compiling and Running a Java Program with a Native Method

## Step 6: Run the Program

> Now run the Java application (the `HelloWorld` class) with the Java interpreter, as follows:

> >     java HelloWorld

> You should see the following output:

> >     Hello World!

> If you see an exception like the following, then you don't have your library path set up correctly.

> >     java.lang.UnsatisfiedLinkError: no hello in shared library path
> >             at java.lang.Runtime.loadLibrary(Runtime.java)
> >             at java.lang.System.loadLibrary(System.java)
> >             at
> >             at java.lang.Thread.init(Thread.java)

> The library path is a list of directories that the Java runtime system searches when loading libraries. Set your library path now, and make sure that the name of the directory where the `hello` library lives is in it.
