### Question:
ByteAccessor implements PropertyAccessor<Byte> { @Override public String toString(Object object) { return object != null ? object.toString() : 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 testToStringObject() { Assert.assertNull(accessor.toString(null)); Byte v1 = new Byte("7"); String s = accessor.toString(v1); Assert.assertEquals("7", s); }
