Which do you prefer of these two? The goal is the same. If bar
is null then make foo
null and avoid the exception. In other languages there is the ?.
operator to help with this.
foo = bar == null ? null : bar.baz();
foo = bar != null ? bar.baz() : null;
I ask because I feel like the “English” of the first example is easier to read and has less negations so it is more straightforward, but the second one has the meat of the expression (bar.baz()
) more prominently.
Yes, Java allows lazy final like you say. I also prefer full blown if when it is non trivial or longer than a full line. (Wish we had if-expressions!)
