In no case will it return a String of length greater than Note that this left edge is not necessarily going toīe the leftmost character in the result, or the first character following theĮllipses, but it will appear somewhere in the result. Works like abbreviate(String, int), but allows you to specifyĪ "left edge" offset.

JAVA STRING CODE
Methods in this class include sample code in their Javadoc comments to explain their operation. NullPointerException should be considered a bug in That is to say that a null input will return null.Ī side effect of the null handling is that a StringUtils handles null input Strings quietly. trim - the characters whitespace - the characters defined by Character.isWhitespace(char).space - the space character ( ' ', char 32).The StringUtils class defines certain words related to the number of changes needed to change one String into another compares Strings and reports on their differences abbreviates a string using ellipses or another given String IsAlpha/IsNumeric/IsWhitespace/IsAsciiPrintable.counts the number of occurrences of one String in another UpperCase/LowerCase/SwapCase/Capitalize/Uncapitalize.prepends a prefix to the start of the String if not present appends a suffix to the end of the String if not present Searches a String and replaces one String with another splits a String into an array of substrings and vice versa substring extraction relative to other strings SubstringBefore/SubstringAfter/SubstringBetween.checks if String contains only/none/any of these characters IndexOfAny/LastIndexOfAny/IndexOfAnyBut/LastIndexOfAnyBut.check if a String ends with a suffix in a null-safe manner check if a String starts with a prefix in a null-safe manner compares two strings in a null-safe manner removes leading and trailing whitespace
