Which is faster, try catch or if-else in java (WRT performance)

Question

Which one is faster:

Either this

try {
  n.foo();
} 
catch(NullPointerException ex) {
}

or

if (n != null) n.foo();         


        

Answer 1

If n.foo() happens to throw internally a NPE, you are off for a long debugging session (or worse, your app fails in production..). Just don't do it.

How many nano-seconds do you plan to save, anyways?
