Every local variable declaration statement is immediately contained by a

block. Local variable declaration statements may be intermixed freely with other

kinds of statements in the block.

A local variable declaration can also appear in the header of a

for

 statement

( 14.12). In this case it is executed in the same manner as if it were part of a local

variable declaration statement.

14.3.1   Local Variable Declarators and Types

Each

declarator

 in a local variable declaration declares one local variable, whose

name is the

Identifier

 that appears in the declarator.

The type of the variable is denoted by the

Type

 that appears at the start of the

local variable declaration, followed by any bracket pairs that follow the

Identifier

in the declarator. Thus, the local variable declaration:

int a, b[], c[][];

is equivalent to the series of declarations:

int a;

int[] b;

int[][] c;

Brackets are allowed in declarators as a nod to the tradition of C and C++. The

general rule, however, also means that the local variable declaration:

float[][] f[][], g[][][], h[];

//

Yechh!

is equivalent to the series of declarations:
