Difference between null==object and object==null

There is no semantical difference.

object.getItems() == null and null == object.getItems() are equivalent.

Perhaps you're mixing it up with the fact that

nonNullObj.equals(obj)

and

obj.equals(nonNullObj)

can make a difference (since the second alternative could result in a NPE in case the callee is null).
