### Question:
Util { @VisibleForTesting static byte convert6BitCharToStandardAscii(byte byteToConvert) { byte b = 0; if (byteToConvert < 32) { b = (byte) (byteToConvert + 64); } else if (byteToConvert < 63) { b = byteToConvert; } return b; } private  Util(); static void checkLatLong(double lat, double lon); static void checkLat(double lat); static void checkLong(double lon); static void checkArgument(boolean b, String message); static AisExtractorFactory getAisExtractorFactory(); static void checkMessageId(int messageId, AisMessageType... messageTypes); static boolean areEqual(int i, int j); static boolean isClassAPositionReport(int messageId);  }### Answer:
@Test public void testConvert6BitToAscii() { Byte value = Util.convert6BitCharToStandardAscii((byte) 65); assertTrue(value.equals((byte) 0)); }
