### Question:
Inches extends Length { @Override public Inches clone() { return (Inches)super.clone(); } Inches(double in);  Inches(Length dist); @Override Inches clone(); @Override String getLongLabel(boolean plural); @Override String getShortLabel(boolean plural); @Override double inFeet(); static final int INCHES_PER_FOOT; static final String INCHES_LONG_LABEL; static final String INCHES_SHORT_LABEL; }### Answer:
@Test public void testClone() { Length dist = new Inches(63360.); Assert.assertEquals(dist.getMagnitude(), dist.clone().getMagnitude(), 0.); }
