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 §10, TYPE, ARRAY_INIT, Constant Field Values

EXTENDS_CLAUSE
```

```
parses as:
```
 +--EXTENDS_CLAUSE
     |
     +--DOT (.)
         |
         +--DOT (.)
             |
             +--IDENT (java)
             +--IDENT (util)
         +--IDENT (LinkedList)
 
```
See Also:

IDENT, DOT, CLASS_DEF, INTERFACE_DEF, FullIdent, Constant Field Values

IMPLEMENTS_CLAUSE
```
public static final int IMPLEMENTS_CLAUSE
```

```
 +--IMPLEMENTS_CLAUSE
     |
     +--IDENT (Serializable)
     +--COMMA (,)
