difference between null != something and something != null

Question

Is there a difference between null != something and something != null in Java. And if there is a difference then which one should I use and why??

Answer 1

There's no difference between null != something and something != null. You must be thinking about the person.getName().equals("john") and the "john".equals(person.getName()) difference: the first one will throw a NullPointerException if getName() returns null, while the second won't. But this is not applicable for the example of your question.
