### Question:
AngleUnitsProvider extends AbstractUnitsProvider<Coordinates> { @Override public Class<? extends Coordinates> getUnitsWithLongLabel(String label) { Lock lock = getLock(); lock.lock(); try { for (Class<? extends Coordinates> type : getAvailableUnitsUnsync()) { try { if (Coordinates.getLongLabel(type).equalsIgnoreCase(label) || Coordinates.getLongLabel(type).equalsIgnoreCase(label)) { return type; } } catch (InvalidUnitsException e) { throw new ImpossibleException(e); } } return null; } finally { lock.unlock(); } } AngleUnitsProvider(); @Override T convert(Class<T> desiredType, Coordinates source); @Override T fromUnitsAndMagnitude(Class<T> type, Number magnitude); @Override Class<? extends Coordinates> getDisplayClass(Coordinates value); @Override String getLongLabel(Class<? extends Coordinates> type, boolean plural); @Override String getSelectionLabel(Class<? extends Coordinates> type); @Override String getShortLabel(Class<? extends Coordinates> type, boolean plural); @Override Class<Coordinates> getSuperType(); @Override Class<? extends Coordinates> getUnitsWithLongLabel(String label); @Override String toShortLabelString(Coordinates obj);  }### Answer:
@Test public void testGetAngleWithLongLabel() { Assert.assertEquals(DecimalDegrees.class, new AngleUnitsProvider().getUnitsWithLongLabel(DecimalDegrees.DEGREES_LONG_LABEL)); Assert.assertEquals(DegreesMinutesSeconds.class, new AngleUnitsProvider().getUnitsWithLongLabel(DegreesMinutesSeconds.DMS_LONG_LABEL)); }
