How do Java developers change lightbulbs?
First they create an instance of ...
I'm afraid, you'll have to get used to that certain tasks (involving
classes of the standard library) are not done the straightforward way,
but by abstrahizing the problem "beyond recognition", and then throwing
some use-once instances at it. ;-)
Posting about perceived imperfections of Java here in cljp typically
has one of these outcomes:
- If you just missed something simple, you'll be told so. :-)
That's why it is often good to ask here.
- Otherwise, you're told of some roundabout way to do it - and will
be seen as a troll if you comment on the roundaboutedness per se.
One should always measure it. And measuring indeed often shows
that the roundabout way isn't all that bad after all. If it is,
then you're suggested to buy a stronger machine (for you and for
all those who will run your code).
What one can be entirely sure won't happen under any circumstances
for a deficiency posted here:
- The straightforward solution will be implemented in Java.
A feature request on oracle's site might have had little more than
zero-chance, if also avoiding the word "sparse" in the description.
