### Question:
PMMLUtils { public static PMML buildSkeletonPMML() { String formattedDate = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZZ", Locale.ENGLISH).format(new Date()); Header header = new Header() .setTimestamp(new Timestamp().addContent(formattedDate)) .setApplication(new Application("Oryx")); return new PMML(VERSION, header, null); } private  PMMLUtils(); static PMML buildSkeletonPMML(); static void write(PMML pmml, Path path); static void write(PMML pmml, OutputStream out); static PMML read(Path path); static PMML read(InputStream in); static String toString(PMML pmml); static PMML fromString(String pmmlString); static final String VERSION; }### Answer:
@Test public void testSkeleton() { PMML pmml = PMMLUtils.buildSkeletonPMML(); assertEquals("Oryx", pmml.getHeader().getApplication().getName()); assertNotNull(pmml.getHeader().getTimestamp()); }
