\section sec_exapi_desc Examples Description
The C, FORTRAN and Java examples below point to the examples in the hdf5-examples github repository. Examples for older versions of HDF5
are handled by setting the appropriate USE_API_xxx definition. HDF5-1.6 examples are in a "16"-named subdirectory.

The Java examples are in the develop source code, and the Java Object package examples are in the HDFView source.
<em>Please note that you must comment out the "package" statement at the top when downloading a Java Object example individually.</em>

The MATLAB and Python examples were generously provided by a user and are not tested.

Languages are C, Fortran, Java (JHI5), Java Object Package, Python (High Level), and Python (Low Level APIs).
