Java Language Specification §7.4, DOT, IDENT, SEMI, ANNOTATIONS, FullIdent, Constant Field Values

ARRAY_DECLARATOR

public static final int ARRAY_DECLARATOR
An array declaration.

If the array declaration represents a type, then the type of the array elements is the first child. Multidimensional arrays may be regarded as arrays of arrays. In other words, the first child of the array declaration is another array declaration.

For example:

   int[] x;
 

parses as:

 +--VARIABLE_DEF
     |
     +--MODIFIERS
     +--TYPE
         |
         +--ARRAY_DECLARATOR ([)
             |
             +--LITERAL_INT (int)
     +--IDENT (x)
 +--SEMI (;)
 

The array declaration may also represent an inline array definition. In this case, the first child will be either an expression specifying the length of the array or an array initialization block.

See Also:
Java Language Specification Chapter 10, TYPE, ARRAY_INIT, Constant Field Values

         |
         +--DOT (.)
             |
             +--IDENT (java)
