Returns: an array of the tokens (null if the input String was null) See Also: StringTokenizer, String.trim(), delimitedListToStringArray(java.lang.String, java.lang.String) delimitedListToStringArray public static String[] delimitedListToStringArray(String str, String delimiter) Take a String which is a delimited list and convert it to a String array. A single delimiter can consists of more than one character: It will still be considered as single delimiter string, rather than as bunch of potential delimiter characters - in contrast to tokenizeToStringArray. Parameters: str - the input String delimiter - the delimiter between elements (this is a single delimiter, rather than a bunch individual delimiter characters) Returns: an array of the tokens in the list See Also: tokenizeToStringArray(java.lang.String, java.lang.String) delimitedListToStringArray public static String[] delimitedListToStringArray(String str, String delimiter, String charsToDelete) Take a String which is a delimited list and convert it to a String array. A single delimiter can consists of more than one character: It will still be considered as single delimiter string, rather than as bunch of potential delimiter characters - in contrast to tokenizeToStringArray. Parameters: str - the input String delimiter - the delimiter between elements (this is a single delimiter, rather than a bunch individual delimiter characters) charsToDelete - a set of characters to delete. Useful for deleting unwanted line breaks: e.g. "\r\n\f" will delete all new lines and line feeds in a String. Returns: an array of the tokens in the list See Also: tokenizeToStringArray(java.lang.String, java.lang.String) commaDelimitedListToStringArray public static String[] commaDelimitedListToStringArray(String str) Convert a CSV list into an array of Strings. Parameters: str - the input String Returns: an array of Strings, or the empty array in case of empty input commaDelimitedListToSet public static Set<String> commaDelimitedListToSet(String str) Convenience method to convert a CSV string list to a set. Note that this will suppress duplicates. Parameters: str - the input String Returns: a Set of String entries in the list collectionToDelimitedString public static String collectionToDelimitedString(Iterable coll, String delim, String prefix, String suffix) Convenience method to return a Collection as a delimited (e.g. CSV) String. E.g. useful for toString() implementations. Parameters: coll - the Collection to display delim - the delimiter to use (probably a ",") prefix - the String to start each element with suffix - the String to end each element with Returns: the delimited String collectionToDelimitedString public static String collectionToDelimitedString(Iterable coll, String delim) Convenience method to return a Collection as a delimited (e.g. CSV) String. E.g. useful for toString() implementations. Parameters: coll - the Collection to display delim - the delimiter to use (probably a ",") Returns: the delimited String collectionToCommaDelimitedString public static String collectionToCommaDelimitedString(Iterable coll) Convenience method to return a Collection as a CSV String. E.g. useful for toString() implementations. Parameters: coll - the Collection to display Returns: the delimited String arrayToDelimitedString public static String arrayToDelimitedString(Object[] arr, String delim) Convenience method to return a String array as a delimited (e.g. CSV) String. E.g. useful for toString() implementations. Parameters: arr - the array to display delim - the delimiter to use (probably a ",") Returns: the delimited String arrayToCommaDelimitedString public static String arrayToCommaDelimitedString(Object[] arr) Convenience method to return a String array as a CSV String. E.g. useful for toString() implementations. Parameters: arr - the array to display Returns: the delimited String format1Decimals public static String format1Decimals(double value, String suffix) Format the double value with a single decimal points, trimming trailing '.0'. toCamelCase public static String toCamelCase(String value) toCamelCase public static String toCamelCase(String value, boolean upperFirst) toCamelCase public static String toCamelCase(String value, StringBuilder sb) toCamelCase public static String toCamelCase(String value, StringBuilder sb, boolean upperFirst) toUnderscoreCase public static String toUnderscoreCase(String value) toUnderscoreCase public static String toUnderscoreCase(String value, StringBuilder sb) extractFieldFromGetSetMethod public static String extractFieldFromGetSetMethod(String methodName) numberToString public static Object numberToString(Object abc) stringToNumber public static Object stringToNumber(Object abc)
