### Question:
Feet extends Length { @Override public Feet clone() { return (Feet)super.clone(); } Feet(double feet);  Feet(Length dist); @Override Feet clone(); @Override String getLongLabel(boolean plural); @Override String getShortLabel(boolean plural); @Override double inFeet(); static final String FEET_LONG_LABEL1; static final String FEET_LONG_LABEL2; static final String FEET_SHORT_LABEL; }### Answer:
@Test public void testClone() { Length dist = new Feet(5280.); Assert.assertEquals(dist.getMagnitude(), dist.clone().getMagnitude(), 0.); }
