JAVA CERTIFICATION QUESTION: Anonymous inner class instantiation

Given:

Which statement is correct, choose one.

* It compiles and prints nothing

* It compiles and prints 'Foo'

* It compiles and prints 'Bar'

* It compiles with 'Foo foo = OcpW47.new Foo(){' at line n1

* It compile with 'Foo foo = new OcpW47.Foo(){' at line n1

Answer:

It compiles and prints 'Bar'

Foo is an inner class, not a static nested one.

So the syntax of the declaration is valid.

The instantiation used an anonynous class that redefines the behavior of the 'm()' method.

So it prints 'Bar'.
