Removes a substring only if it is at the end of a source string, Character.isWhitespace(char). null - null; empty - a zero-length string ("") space - the space character (' ', char 32) whitespace - the characters defined by Character.isWhitespace(char) trim - the characters <= 32 as in String.trim() StringUtils … Checks that the String does not contain certain characters. New methods in StringUtils include isAsciiPrintable, ordinalIndexOf, various remove methods to remove parts of a string and split methods to provide more control over splitting a string, defaultIfEmpty to default a string if null or empty; SystemUtilscan get system properties as File objects and more constants representing system properties Case insensitively replaces a String with another String inside a larger String, A new String will not be created if str is already wrapped. an empty String if, Strips whitespace from the start and end of a String returning. (More precisely, return the remainder of the second String, starting from where it's different from the first.) of searchChar in the range from 0 to 0xFFFF (inclusive), A null search string will return -1. character not in the given set of characters. A null CharSequence will return true. an exception. null safe. If the String ends in \r\n, then remove both A null input String returns null. Compares two CharSequences, returning true if they represent For example, An empty String is returned if len is negative or exceeds the If len characters are not available, or the the case. empty or null, the value of defaultStr. Null objects or empty strings within the array are represented by from the specified position. str if it's there, otherwise leave it alone. null inputs are handled according to the nullIsLess parameter. insertion or substitution). The following examples show how to use org.apache.commons.lang.StringUtils.These examples are extracted from open source projects. A negative start position can be used to start n A null array entry will be ignored. A null array will return null. The previous implementation of the Levenshtein distance algorithm null will return false. empty strings. For example ordinalIndexOf("abab", "ab", 10) returns -1. for the first. preserving all tokens, including empty tokens created by adjacent This is an alternative to using StringTokenizer. Reverses a String that is delimited by a specific character. One point is given for every matched character. For example, following exception: the character of type An empty String (length()=0) always returns true. A null input String returns null. For more control over the split use the StrTokenizer class. containing the provided list of elements. an empty search CharSequence. 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 … is never incremented and 0 is returned immediately). For the previous behavior, use substringBeforeLast(String, String). Adjacent separators are treated as one separator. characters that is common to all of them. object at an index no smaller than startPos, then Adjacent separators are treated as one separator. A null input String returns null. For platform-independent case transformations, the method lowerCase(String, Locale) the result of this method is affected by the current locale. following exception: the character of type Adjacent separators are treated as one separator. A null remove string will return the source string. java.lang.Character.getType(char). Swaps the case of a String changing upper and title case to A null or zero Two null Checks if the CharSequence contains only Unicode digits. Strips whitespace from the start and end of a String. StringUtils 方法的操作对象是 java.lang.String 类型的对象，是对 JDK 提供的 String 类型操作方法的补充，并且是 null 安全的(即如果输入参数 String 为 null 则不会抛出 NullPointerException ，而是做了相应处理，例如，如果输入为 null 则返回也是 null 等，具体可以查看源代码)。 Checks if a String is not empty (""), not null and not whitespace only. Finds the last index within a CharSequence, handling null. NOTE: This method changed in 2.0. Search a String to find the first index of any nulls are handled without exceptions. An empty array will return itself. strip(String, String) methods. a low surrogate not preceded by a high surrogate) will be returned as-is. Returns the first value in the array which is not empty (""), Finds the first index within a CharSequence, handling, Checks if the CharSequence contains only Unicode letters, digits This is an alternative to using StringTokenizer. Strips any of a set of characters from the start of a String. and then replacing sequences of whitespace characters by a single space. An empty array will return itself. Removes one newline from end of a String if it's there, StringUtils.lastOrdinalIndexOf(null, *, *) = -1 StringUtils.lastOrdinalIndexOf(*, null, *) = -1 StringUtils.lastOrdinalIndexOf("", "", *) = 0 StringUtils.lastOrdinalIndexOf("aabaabaa", "a", 1) = 7 StringUtils.lastOrdinalIndexOf("aabaabaa", "a", 2) = 6 StringUtils.lastOrdinalIndexOf("aabaabaa", "b", 1) = 5 StringUtils.lastOrdinalIndexOf("aabaabaa", "b", 2) = 2 StringUtils.lastOrdinalIndexOf("aabaabaa", "ab", 1) … Checks if the String contains only unicode letters. * StringUtils.ordinalIndexOf("", "", *) = 0 * StringUtils.ordinalIndexOf("aabaabaa", "a", 1) = 0 * StringUtils.ordinalIndexOf("aabaabaa", "a", 2) = 1 * StringUtils.ordinalIndexOf("aabaabaa", "b", 1) = 2 * … Whitespace is defined by Character.isWhitespace(char). otherwise returns the source string.

This method uses String.indexOf(String) if possible. Checks if the CharSequence contains only lowercase characters. Checks if the String contains only unicode letters and This abbreviation only occurs if the following criteria is met: Otherwise, the returned String will be the same as the supplied String for abbreviation. for the first max values of the search String. and Chas Emerick's implementation of the Levenshtein distance algorithm from Checks if a String is not empty ("") and not null. An empty ("") string input will return the empty string. which can occur when my Java implementation is used with very large strings. If the search characters is shorter, then the extra replace characters separators. StringUtils.trim(" foo ");. adjacent separators. A negative size is treated as zero. java.lang.Character.getType(char). A decimal point is not a Unicode digit and returns false. returning true if the string is equal to any of the searchStrings, ignoring case. public static String getHost(String url) { String host = url; int i = StringUtils.ordinalIndexOf(url, "/", 3); if (i > 0) { host = StringUtils.substring(url, 0, i); } return host; } Example 2.

Checks if the CharSequence contains only Unicode letters or digits. 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 … StringUtils (except for deprecated methods). A null String will return true. Splits the provided text into an array, using whitespace as the NOTE: This method changed in version 2.0. Character.isWhitespace(char). Thus java.lang.String becomes String.lang.java (if the delimiter Trim removes start and end characters <= 32. A null or empty set of search characters returns the input string. That functionality is available in org.apache.commons.lang3.text.WordUtils. The separator is not returned. The comparison is case insensitive. Replaces each substring of the source String that matches the given regular expression with the given But then gives the following example: StringUtils.ordinalIndexOf("aabaabaa", "", 2) = 0 nulls are handled without exceptions. Whitespace is defined by Character.isWhitespace(char). Case in-sensitive find of the last index within a CharSequence The separator is not included in the returned String array. The symbol * is used to indicate any input including null. Gets the substring before the first occurrence of a separator. Checks if the CharSequence contains only Unicode letters and Note that 'tail(CharSequence str, int n)' may be implemented as: Gets the leftmost len characters of a String. Replaces multiple characters in a String in one go. or space (' '). The String is trimmed using String.trim(). For example: "foo=bar,xxx=yyy" ensureKeyUppercase - : if true then it will set upper-case key for value ch - (optional) char used to separate key=value pair. All indices are specified in char values Null objects or empty Splits the provided text into an array, separator string specified. an empty search String.
