### Question:
LandsatGeotiffReaderPlugin implements ProductReaderPlugIn { @Override public Class[] getInputTypes() { return READER_INPUT_TYPES; }  @Override DecodeQualification getDecodeQualification(Object input); @Override Class[] getInputTypes(); @Override ProductReader createReaderInstance(); @Override String[] getFormatNames(); @Override String[] getDefaultFileExtensions(); @Override String getDescription(Locale locale); @Override BeamFileFilter getProductFileFilter(); static VirtualDir getInput(Object input);  }### Answer:
@Test public void testGetInputTypes() { final LandsatGeotiffReaderPlugin plugin = new LandsatGeotiffReaderPlugin(); final Class[] inputTypes = plugin.getInputTypes(); assertEquals(2, inputTypes.length); assertEquals(String.class, inputTypes[0]); assertEquals(File.class, inputTypes[1]); }
