public class WhitespaceAfterCheck extends AbstractCheck
Checks that a token is followed by whitespace, with the exception that it
does not check for whitespace after the semicolon of an empty for iterator.
Use Check EmptyForIteratorPad

empty for iterators.
By default the check will check the following tokens:
COMMA
,
SEMI
,
TYPECAST
,
LITERAL_IF
,
LITERAL_ELSE
,
LITERAL_WHILE
,
LITERAL_FOR
,
LITERAL_DO

An example of how to configure the check is:

<module name="WhitespaceAfter"> <property name="tokens" value="COMMA, SEMI"/> </module>
