GDAL is both an API and a set of command line utilities (written from
the API itself).
The API is exposed by several languages binding, Java included.
You could try to do the following (code in Python, but easily
convertible to Java):
>>> from osgeo import gdal, osr
>>> ds = gdal.Open('landcover.img', 0)
>>> prj = ds.GetProjectionRef()
>>> srs = osr.SpatialReference(prj.title())
>>> print srs.GetAuthorityCode('GEOGCS') # or use PROJCS if the srs is projected
