then class Point4d would inherit the field z , which, being public , could then be accessed
by code in packages other than morePoints , through variables and expressions of the
public type Point4d .
8.3. Field Declarations
The variables of a class type are introduced by field declarations .
FieldDeclaration:
FieldModifiers opt Type VariableDeclarators ;
VariableDeclarators:
VariableDeclarator
VariableDeclarators , VariableDeclarator
VariableDeclarator:
VariableDeclaratorId
VariableDeclaratorId = VariableInitializer
VariableDeclaratorId:
Identifier
VariableDeclaratorId [ ]
VariableInitializer:
Expression
ArrayInitializer
The FieldModifiers are described in § 8.3.1 .
The Identifier in a FieldDeclarator may be used in a name to refer to the field.
More than one field may be declared in a single field declaration by using more than one
declarator; the FieldModifiers and Type apply to all the declarators in the declaration.
The declared type of a field is denoted by the Type that appears in the field declaration,
followed by any bracket pairs that follow the Identifier in the declarator.
It is a compile-time error for the body of a class declaration to declare two fields with the
same name.
The scope and shadowing of a field declaration is specified in § 6.3 and § 6.4 .
If the class declares a field with a certain name, then the declaration of that field is said to
hide any and all accessible declarations of fields with the same name in superclasses, and
superinterfaces of the class.
