To be honest, I didn't try but it looks like the method is available :

http://gdal.org/java/org/gdal/gdal/gdal.html#Translate(java.lang.String,%20org.gdal.gdal.Dataset,%20org.gdal.gdal.TranslateOptions)

and I can see it in the generated .java files from swig files.

(Contributions in 2017 are as welcome as in previous years ! Hint: the file to edit is swig/java/javadoc.java and
the the doc is built with swig/java/make_doc.sh)

The general principles are exposed
here https://trac.osgeo.org/gdal/wiki/rfc59.1_utilities_as_a_library and should be
transposable to other languages.

try

optionsVector.add("-of");
optionsVector.add("PNG");
optionsVector.add("-outsize");
optionsVector.add("128");
optionsVector.add("128");
