Not unless that's something new (no pun intended); "new Bar()" simply 
calls the Bar constructor to generate a new instance of class Bar, and 
"foo = new Bar();" does that, and pours the new instance of Bar into 
some variable called foo. If it also implicitly declares foo to be a 
variable typed to hold an object of class Bar, then this is the first 
I've heard of it.

Then again, just about anytime I look at non-trivial Java source, I see 
constructs I've never seen before, that have me scratching my head.

(Oh, and a constructor is not a method; it's a constructor, sort of the 
way the King is not a subject, he's the King. [Apologies to Ben Jonson.] 
And methods don't have constructors; classes have them.)
