An

AmbiguousName

 is then reclassified as follows:

If the

AmbiguousName

 is a simple name, consisting of a single

Identifier

:

N

If the

Identifier

 appears within the scope ( 6.3) of a local variable declara 

tion ( 14.3) or parameter declaration ( 8.4.1,  8.6.1,  14.18) with that

name, then the

AmbiguousName

 is reclassified as an

ExpressionName

.

N

Otherwise, consider the class or interface

C

 within whose declaration the

Identifier

 occurs. If

C

 has one or more fields with that name, which may be

either declared within it or inherited, then the

AmbiguousName

 is reclassi 

fied as an

ExpressionName

.

N

Otherwise, if a type of that name is declared in the compilation unit ( 7.3)

containing the

Identifier

, either by a single type import declaration ( 7.5.1)

or by a class or interface type declaration ( 7.6), then the

AmbiguousName

is reclassified as a

TypeName

.

N

Otherwise, if a type of that name is declared in another compilation unit

( 7.3) of the package ( 7.1) of the compilation unit containing the

Identifier

, then the

AmbiguousName

 is reclassified as a

TypeName

.

N

Otherwise, if a type of that name is declared by exactly one type import on 

demand declaration ( 7.5.2) of the compilation unit containing the

Identifier

, then the

AmbiguousName

 is reclassified as a
