Summary: lazy initialization

Initial Comment:
It's common to do this for lazy initialization:
?Blah blah = null;
if (blah == null)
    blah = new Blah();
blah.doThis();

However, this fails because the compiler thinks that
blah maybe null when you call blah.doThis().

If I declare blah as Blah (without ?), then the
compiler complains that I am comparing blah with null
(blah == null).

There should be a way to do this without using a
separate boolean variable to check if blah has been
initialized.
