### Question:
UUIDAccessor implements PropertyAccessor<UUID> { @Override public String toString(Object object) { if (object == null) { return null; } return ((UUID) object).toString(); }  @Override UUID fromBytes(Class targetClass, byte[] bytes); @Override byte[] toBytes(Object object); @Override String toString(Object object); @Override UUID fromString(Class targetClass, String s); @Override UUID getCopy(Object object); UUID getInstance(Class<?> clazz); static Logger log; }### Answer:
@Test public void testToStringObject() { Assert.assertNull(accessor.toString(null)); UUID uuid = UUID.randomUUID(); String s1 = uuid.toString(); String s2 = accessor.toString(uuid); Assert.assertTrue(s1.equals(s2)); }
