| public static java.util.List | parseStringList(java.lang.String line)Parses a string containing substrings separated from
each other by the standard separator characters and returns
a list of strings.
Splits the string line into individual string elements
separated by the field separators, and returns these individual
strings as a list of strings. The individual string elements are
trimmed of leading and trailing whitespace. Only non-empty strings
are returned in the list.

| public static java.util.List | parseStringList(java.lang.String line, java.lang.String sep)Parses a string containing substrings separated from
each other by the specified set of separator characters and returns
a list of strings.
Splits the string line into individual string elements
separated by the field separators specified in sep,
and returns these individual strings as a list of strings. The
individual string elements are trimmed of leading and trailing
whitespace. Only non-empty strings are returned in the list.
