public class ArrayTypeStyleCheck extends AbstractCheck
Checks the style of array type definitions. Some like Java style: public static void main(String[] args) and some like C style: public static void main(String args[]).

By default, the Check enforces Java style.

This check strictly enforces only Java style for method return types regardless of the value for 'javaStyle'. For example, byte[] getData(). This is because C doesn't compile methods with array declarations on the name.

  • Property javaStyle - Control whether to enforce Java style (true) or C style (false). Type is boolean. Default value is true.
