++ To configure check to restrict use of whitespace after ARRAY_DECLARATOR token: +
+ ++<module name="NoWhitespaceAfter"> + <property name="tokens" value="ARRAY_DECLARATOR"/> +</module> +
Example:
+ ++int [] array1; // violation, whitespace after 'int' is not allowed +int[] array2; // OK +int[ ] array3; // OK +int array4 []; // violation, whitespace after 'array4' is not allowed +int array5[]; // OK +int array6[ ]; // OK +

+ ++<module name="NoWhitespaceAfter"> + <property name="tokens" value="ARRAY_DECLARATOR"/> + <property name="allowLineBreaks" value="false"/> +</module> +
Example:
+ ++int + [] array1; // violation, linebreak after 'int' is not allowed +int[ + ] array2; // OK +int array3 + []; // violation, linebreak after 'a' is not allowed +int array4[ + ]; // OK +
+ To configure check to restrict use of whitespace after ARRAY_INIT token: +

Example:

+int[] array1 = { 1, 2, 3, 4}; // violation, whitespace after '{' is not allowed

+int[][] array3 = {{ 1,2}, {3,4}} // violation, whitespace after '{' is not allowed
