### PACKAGE_DEF

    public static final int PACKAGE_DEF

  The package declaration. This is optional, but if it is included, then there is only one package declaration per source file and it must be the first non-comment in the file. A package declaration may be annotated in which case the annotations comes before the rest of the declaration (and are the first children).

  For example:

         package com.puppycrawl.tools.checkstyle.api;

  parses as:

       +--PACKAGE_DEF (package)
           |

    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

### EXTENDS_CLAUSE

    public static final int EXTENDS_CLAUSE

  An extends clause. This appear as part of class and interface definitions. This element appears even if the `extends` keyword is not explicitly used. The child is an optional identifier.
