NAMES

Meaning of Expression Names

6.5.5

In this example:

The name

wnj.test

 must name a package on the host system. It is resolved

by first looking for the package

wnj

, using the procedure described in

 6.5.3.1, and then making sure that the subpackage

test

 of this package is

accessible.

The name

java.util.Date

 ( 21.3) must denote a type, so we first use the

procedure recursively to determine if

java.util

 is an accessible package,

which it is, and then look to see if the type

Date

 is accessible in this package.

6.5.5   Meaning of Expression Names

The meaning of a name classified as an

ExpressionName

 is determined as follows.

6.5.5.1

Simple Expression Names

If an expression name consists of a single

Identifier

, then:

If the

Identifier

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

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

the expression name denotes a variable, that is, that local variable or parame 

ter. Local variables and parameters are never hidden ( 6.3,  6.3.1,  14.3), so

there is necessarily at most one such local variable or parameter. The type of

the expression name is the declared type of the local variable or parameter.

Otherwise, if the

Identifier

 appears within a class declaration ( 8):

N

If there is not exactly one member of that class ( 8.2) that is a field with that

name, then a compile time error results.

N

Otherwise, if the single member field with that name is declared

final

( 8.3.1.2), then the expression name denotes the value of the field. The type

of the expression name is the declared type of the field. If the

Identifier

appears in a context that requires a variable and not a value, then a compile 

time error occurs.

N

Otherwise, the expression name denotes a variable, the single member field

with that name. The type of the expression name is the field's declared type.

If the field is an instance variable ( 8.3.1.1), the expression name must appear

within the declaration of an instance method ( 8.4), constructor ( 8.6), or

instance variable initializer ( 8.3.2.2). If it appears within a

static

 method

( 8.4.3.2), static initializer ( 8.5), or initializer for a

static

 variable

( 8.3.1.1,  12.4.2), then a compile time error occurs.
