if(null check)-else vs try catch(NullPointerException) which is more efficient?

Question

Which of the following three functions is more efficient;

  public String getmConnectedDeviceName1() {
        if(null != mServerDevice) {
            retur         


        

Answer 1

Using try-catch clause definitely not a better way.

Also try-catch results in instantiating of new object (the exception). And also if else improves the readability. Thus I'd say that (n!=null) is faster in case you have a lot of cases where n == null. Also n!=null is superfast construct.
