### Question:
StatuteMiles extends Length { @Override public StatuteMiles clone() { return (StatuteMiles)super.clone(); } StatuteMiles(double mi);  StatuteMiles(Length dist); static double fromFeet(double feet); static double toFeet(double miles); @Override StatuteMiles clone(); @Override String getLongLabel(boolean plural); @Override String getShortLabel(boolean plural); @Override double inFeet(); static final int FEET_PER_STATUTE_MILE; static final String MILES_LONG_LABEL; static final String MILES_SHORT_LABEL; }### Answer:
@Test public void testClone() { Length dist = new StatuteMiles(1.); Assert.assertEquals(dist.getMagnitude(), dist.clone().getMagnitude(), 0.); }
