### Question:
ByteAccessor implements PropertyAccessor<Byte> { @Override public Byte getCopy(Object object) { return object != null ? new Byte((Byte) object) : null; }  @Override Byte fromBytes(Class targetClass, byte[] b); @Override byte[] toBytes(Object object); @Override String toString(Object object); @Override Byte fromString(Class targetClass, String s); @Override Byte getCopy(Object object); Byte getInstance(Class<?> clazz);  }### Answer:
@Test public void testGetCopy() { Assert.assertNull(accessor.getCopy(null)); Byte v1 = new Byte("7"); Byte v2 = accessor.getCopy(v1); Assert.assertEquals(v1, v2); }
