Here is the Code from K&B's inner class section (Page 483)

I am not able to under stand the syntax (new Bar(){}).go(); used to invoke the inner class method. My understanding is either (new Bar()).go();
or 1. Bar in = new Bar(); 2. in.go() is the right way to invoke the method go() of the inner class. Confusion is the {} braces after the new Bar(){}.
Can any one explain me this please. My Head is spinning with inner class concept

The line you mention: (new Bar(){}).go(); creates an anonymous inner class that extends the inner class Bar. It is no different than just writing (new Bar()).go(); since the go method is not overriden. This may make more sense to you:
