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

Point of view of performance there will be no difference, both sides of the operator are executed any way. But for a more readable code second one seems more readable

  obj.getSomething().getAnotherThing().doSomething() != null

  null != obj.getSomething().getAnotherThing().doSomething()

But if you are going to just compare a variable or parameter this is more readable

  something != null

Of course this depends on sense of reader.
