[CORE] ClassInstanceCreation grammar question [message #62854]

Given:

ClassInstanceCreation:
[ Expression . ] new TypeName
( [ Expression { , Expression } ] )
[ AnonymousClassDeclaration ]

as the grammar for a ClassInstanceCreation per the JavaDoc in
ClassInstanceCreation,

I'm confused about what valid Java code would parse using the initial

[ Expression . ]

part of the grammar. Or even where I would go to find out.

I'd be most appreciative if someone could just post an example of valid
Java code that would parse using that optional Expression dot at the
beginning of that grammar.

Thanks much in advance,

Dave

Is this kind of example you're looking for?

public class A {
public class B {
public class C {
void foo() {
}
}
}
public static void main(String args[]) {
new A().new B().new C().foo();
}
}
