rpad

public static String rpad(String delimiter,
          String str,
          int max)

This method is used to pad a line by max length with a delimiter.

Parameters:

delimiter - - String that will be used to concatenate to the end of line

str - - string input that will be changed and returned

max - - size of the maximum length of a string

Returns:

rpadByMaxSize

public static String rpadByMaxSize(String delimiter,
                   String str,
                   int max)

When you have a line that has a maximum length and want to pad the remaining space with ' ' whitespace then this method is for you.

Parameters:

delimiter - - String that will be used to concatenate to the end of line

str - - string input that will be changed and returned

max - - size of the maximum length of a string

Returns:

isNullOrBlank

public static boolean isNullOrBlank(String value)

isNotBlank

public static boolean isNotBlank(String text)

stripSuffix

public static String stripSuffix(String value,
                 String suffix)

parseDelimitedString

public static List<String> parseDelimitedString(String value,

parseDelimitedString

public static List<String> parseDelimitedString(String value,
                                String delim,
                                boolean trim)

Parses delimited string and returns an array containing the tokens. This parser obeys quotes, so the delimiter character will be ignored if it is inside of a quote. This method assumes that the quote character is not included in the set of delimiter characters.

Parameters:

value - the delimited string to parse.

delim - the characters delimiting the tokens.

Returns:

a list of string or an empty list if there are none.
