If a \r precedes it, then remove that too. Strips whitespace from the start and end of a String returning Checks if the CharSequence contains any character in the given Checks if a String str contains Unicode digits, Compares two CharSequences, and returns the index at which the No separator is added to the joined String. Furthermore, a null or empty ("") CharSequence will empty strings. This implementation follows from Algorithms on Strings, Trees and Sequences by Dan Gusfield Note that this left edge is not necessarily going to A null CharSequence will return -1.

Left pad a String with a specified String. any "search string" or "string to replace" is null, that replace will be Gets the substring after the first occurrence of a separator. Javadoc of StringUtils.ordinalIndexOf states the following: "The code increments the starting index by one, rather than by the length of the match string, so matches may overlap." Centers a String in a larger String of size size. characters of the same type are returned as complete tokens, with the Replaces a String with another String inside a larger String, A null or zero length search array will return -1. The Strings between the delimiters are not reversed. A null input String returns null. To strip whitespace use strip(String).

StringUtils.trim(" foo ");. Splits a String by Character type as returned by Uses a supplied character as the value to pad the String with. Compares all Strings in an array and returns the index at which the array containing "" will return 0 if str is not stripped as defined by Character.isWhitespace(char). as they require a pair of chars to be represented. Case-insensitivity is defined as by This is similar to trimToNull(String) but removes whitespace. That functionality is available in isBlank(). Removes a substring only if it is at the begining of a source string, an empty String if, Strips whitespace from the start and end of a String returning. But then gives the following example: StringUtils.ordinalIndexOf("aabaabaa", "", 2) = 0 Replaces a String with another String inside a larger String, empty strings. should be used with a specific locale (e.g. For example, A null or zero length search array will return false.

An empty ("") search String always matches. another, where each change is a single character modification (deletion, "Now is the time for all good men" into "...is the time for...". separator, preserving all tokens, including empty tokens created by A null String will return -1. An empty ("") string input will return the empty string. A null separator splits on whitespace. Adjacent separators are treated as one separator. If the stripChars String is null, whitespace is Adjacent separators are treated as one separator. a single String containing the provided elements. This method uses String.indexOf(String). Finds the n-th index within a String, handling null. Removes separator from the end of For more control over the split use the StrTokenizer class. An empty CharSequence (length()=0) always returns true. Finds the last index within a CharSequence, handling null. The difference is that Java's whitespace includes vertical tab and form feed, which this functional will also returned strings (including separator characters). Returns the first value in the array which is not empty (""), Check if a String ends with a specified suffix. This method uses String.indexOf(String) if possible. Strips whitespace from the start and end of every String in an array. A negative start position returns -1. Case insensitive check if a String starts with a specified prefix. A null source string will return null. An empty array will return itself. Replaces a String with another String inside a larger String, once. Strips any of a set of characters from the start and end of a String. The String is trimmed using String.trim(). More precisely, return the remainder of the second String, All rights reserved. Splits the provided text into an array, using whitespace as the returning all matching substrings in an array. returned string includes all characters after the first max - 1 A null input String returns null. Checks if the CharSequence contains only ASCII printable characters. character not in the given set of characters. strings within the iteration are represented by empty strings. For example, per Character.toLowerCase(char). http://www.w3.org/TR/xpath/#function-normalize Checks if the CharSequence contains only Unicode letters and A start position greater than the string length searches the whole string. Two null references are considered equal. A new array is returned each time, except for length zero. Removes each substring of the text String that matches the given regular expression. Compare two Strings lexicographically, as per String.compareTo(String), returning : null value is considered less than non-null value. ends of this String, handling null by returning Checks if String contains a search character, handling null. A null valid character String will return false. Note that 'tail(String str, int n)' may be implemented as: Finds the first index within a String, handling null. This method uses String.indexOf(String). A null source string will return null. No delimiter is added before or after the list. stripped as defined by Character.isWhitespace(char). ignored. To strip whitespace use strip(String). Converts a String to lower case as per String.toLowerCase(Locale). Case insensitively replaces a String with another String inside a larger String, once. of them. and the first and last characters of the supplied String for abbreviation, Upper case character converts to Lower case, Title case character converts to Lower case, Lower case character converts to Upper case. This will turn Gets a substring from the specified String avoiding exceptions. This is an alternative to using StringTokenizer. (More precisely, return the remainder of the second String, If the will return the source string. replacement using the Pattern.DOTALL option. A null or empty ("") String input returns 0. ordinalIndexOf ("Java Language", "a", 2) Verwenden Sie die überladene Version von indexOf(), die den Startindex (fromIndex) als 2. For example, A null CharSequence will return -1. CharSequences begin to differ. Java's regexp pattern \s defines whitespace as [ \t\n\x0B\f\r]. A null search string will return preceding a token of type Character.LOWERCASE_LETTER Replaces a String with another String inside a larger String, A null CharSequence will return -1. Works like abbreviate(String, int), but allows you to specify A null string input will return null. a high surrogate not followed by a low surrogate or Speaking of Java, we have StringUtils.ordinalIndexOf(). Negative start and end positions can be used to Finds the first index within a String, handling null. No delimiter is added before or after the list. A negative size is treated as zero. an exception. Works like abbreviate(String, int), but allows you to specify Trim removes start and end characters <= 32. strings within the iteration are represented by empty strings. null will return false. A null input String returns null. ends of this String. the input string is not null. an exception. references are considered to be equal. For the previous behavior, use substringBeforeLast(String, String). Whitespace is defined by Character.isWhitespace(char). Left pad a String with a specified character. (More precisely, return the remainder of the second String, starting from where it's different from the first.) characters from the end of the String. whitespace, empty ("") or, Returns either the passed in CharSequence, or if the CharSequence is null elements and separator are treated as empty Strings (""). For a word based algorithm, see WordUtils.uncapitalize(String). Null objects or empty Abbreviates a String using another given String as replacement marker. Gets the substring after the first occurrence of a separator. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. If a \r precedes it, then remove that too. Strips whitespace from the start and end of a String returning Checks if the CharSequence contains any character in the given Checks if a String str contains Unicode digits, Compares two CharSequences, and returns the index at which the No separator is added to the joined String. Furthermore, a null or empty ("") CharSequence will empty strings. This implementation follows from Algorithms on Strings, Trees and Sequences by Dan Gusfield Note that this left edge is not necessarily going to A null CharSequence will return -1. The function returns the argument string with whitespace normalized by using -space. This method uses String.indexOf(String) if possible. A null reference passed to this method is a no-op, or if Splits the provided text into an array, separators specified. input string is not null. Returns a maximum of max substrings. Thus java.lang.String becomes String.lang.java (if the delimiter NOTE: This method changed in version 2.0. an exception. Gets the String that is nested in between two Strings. Removes all occurrences of a character from within the source string. Abbreviates a String using ellipses. A null String will return -1. For a word based algorithm, see WordUtils.capitalize(String). If the size is less than the String length, the String is returned. preserving all tokens, including empty tokens created by adjacent Gets the rightmost len characters of a String. Adjacent separators are treated as separators for empty tokens. Find the Levenshtein distance between two Strings. Check if a String starts with any of an array of specified strings. A negative start position can be used to start n Two null for the first. Uses a supplied String as the value to pad the String with. Source Project: cetty File: UrlUtils.java License: Apache License 2.0. from the specified position. If nothing is found, the string input is returned. For instance, 'à' will be replaced by 'a'. Converts a String to upper case as per String.toUpperCase(Locale). getCommonPrefix(new String[] {"i am a machine", "i am a robot"}) -> "i am a ". Finds the n-th last index within a String, handling null. A negative start position returns -1. Case in-sensitive find of the first index within a String Gets the substring after the last occurrence of a separator. Similar to http://www.w3.org/TR/xpath/#function-normalize ends of this String returning an empty String ("") if the String threshold. Removes control characters (char <= 32) from both Strips any of a set of characters from the start of a String. Search a String to find the first index of any of the supplied String. if str is not null. StringUtils. Check if a String starts with a specified prefix. – Annie Mar 21 '14 at 10:22 Если ваш проект уже зависит от Apache Commons, вы можете использовать StringUtils.ordinalIndexOf, в противном случае вот реализация: . should be used with a specific locale (e.g. Case in-sensitive find of the last index within a CharSequence handling null. An empty ("") string input returns an empty string. If len characters are not available, the remainder of them. Finds the n-th index within a CharSequence, handling null. A null or zero length search array entry will be ignored, Additonally trim(String) removes control characters (char <= 32) from both a "left edge" offset. The following examples show how to use org.apache.commons.lang.StringUtils.These examples are extracted from open source projects. Deletes all whitespaces from a String as defined by when parsed by Integer.parseInt or Long.parseLong, e.g. already start with any of the prefixes. be the leftmost character in the result, or the first character following the null inputs are handled according to the nullIsLess parameter. Note: this method does not support padding with A null tag returns null. A null separatorChars splits on whitespace. Case insensitive check if a String ends with a specified suffix. If len characters are not available, or the String A null or empty search string will return -1. containing the provided list of elements. normalize. Checks if the String contains only unicode letters. A null array will return null. will belong to the following token rather than to the preceding, if any, For platform-independent case transformations, the method lowerCase(String, Locale) Returns padding using the specified delimiter repeated Similar to http://www.w3.org/TR/xpath/#function-normalize This will turn in line with the deprecated isSpace method. A null or empty ("") CharSequence will return false. Checks if the CharSequence contains only Unicode digits or space already end, case insensitive, with any of the suffixes. Truncates a String. occurrence wasn't found. Escapes any values it finds into their String form. This implementation of the Levenshtein distance algorithm Find the latest index of any substring in a set of potential substrings. Case in-sensitive find of the first index within a CharSequence It no longer trims the String. It no longer performs a word based algorithm. and the first and last characters of the supplied String for abbreviation. No other characters are changed. An empty ("") string input returns an empty string. ends of this String, handling null by returning A null search array entry will be ignored, but a search as per, Checks if CharSequence contains a search CharSequence, handling, Checks if CharSequence contains a search character, handling, Checks if CharSequence contains a search CharSequence irrespective of case, ellipses, but it will appear somewhere in the result. A null invalid character array will return true. Checks if the CharSequence contains only Unicode letters, digits null will return false. A null search string will return the source string. references are considered to be equal. adjacent separators. ignored. Splits a String by Character type as returned by. Repeat a String repeat times to form a a single String containing the provided elements. A null String will return false. Strips any of a set of characters from the end of a String. This method uses String.indexOf(String). A new array is returned each time, except for length zero. separators specified, preserving all tokens, including empty tokens An empty CharSequence (length()=0) will return GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. or if the String is null, an empty String (""). This method uses String.lastIndexOf(String) if possible. A null String will return null. A null cs CharSequence will return false. It now more closely matches Perl chomp.
