Right pad a String with a specified String. Compares two CharSequences, returning true if they represent (More precisely, return the remainder of the second String, starting from where it's different from the first.) This will turn Removes the first substring of the text string that matches the given regular expression. Example: int org.apache.commons.lang.StringUtils.ordinalIndexOf(CharSequence str, CharSequence searchStr, int ordinal) for your problem you can code the following: StringUtils.ordinalIndexOf (uri, "/", 3) You can also find the last nth occurrence of a character in a … A null invalid character array will return true.

Check if a CharSequence starts with any of the provided case-sensitive prefixes. Returns either the passed in String, No delimiter is added before or after the list. A null input String returns null. This implementation follows from Algorithms on Strings, Trees and Sequences by Dan Gusfield Joins the elements of the provided array into a single String An empty ("") remove string will return the source string. Note that this left edge is not necessarily going to Gets the substring after the first occurrence of a separator. No delimiter is added before or after the list. The search starts at the startPos and works backwards; matches starting after the start A null or empty search string will return -1. separators specified. Parameters: csvKeyVal - or other char separated key=value pair. otherwise returns the source string. A decimal point is not a unicode digit and returns false. Checks if a String is empty ("") or null. For example, A null separatorChars splits on whitespace. be the leftmost character in the result, or the first character following the It now more closely matches Perl chomp. new String.
