      • capitalize

      • substringAfterLast

        public static String substringAfterLast​(String str,

      • strip

        public static String strip​(String str,
                           String stripChars)

        Strips any of a set of characters from the start and end of a String. This is similar to String.trim() but allows the characters to be stripped to be controlled.

        A null input String returns null. An empty string ("") input returns the empty string. 

         StringUtils.strip(null, *)          = null
 StringUtils.strip("", *)            = ""
 StringUtils.strip("abc", null)      = "abc"
 StringUtils.strip("  abc", null)    = "abc"
 StringUtils.strip("abc  ", null)    = "abc"
 StringUtils.strip(" abc ", null)    = "abc"
 StringUtils.strip("  abcyx", "xyz") = "  abc"
        Parameters:
        str - the String to remove characters from, may be null
        stripChars - the characters to remove, null treated as whitespace
        Returns:
        the stripped String, null if null String input

      • stripStart

        public static String stripStart​(String str,
                                String stripChars)

        Strips any of a set of characters from the start of a String.

        A null input String returns null. An empty string ("") input returns the empty string.

        If the stripChars String is null, whitespace is stripped as defined by Character.isWhitespace(char). 

         StringUtils.stripStart(null, *)          = null
 StringUtils.stripStart("", *)            = ""
 StringUtils.stripStart("abc", "")        = "abc"
 StringUtils.stripStart("abc", null)      = "abc"
 StringUtils.stripStart("  abc", null)    = "abc"
 StringUtils.stripStart("abc  ", null)    = "abc  "
 StringUtils.stripStart(" abc ", null)    = "abc "
 StringUtils.stripStart("yxabc  ", "xyz") = "abc  "
        Parameters:
        str - the String to remove characters from, may be null
        stripChars - the characters to remove, null treated as whitespace
        Returns:
        the stripped String, null if null String input

      • stripEnd

        public static String stripEnd​(String str,
                              String stripChars)

        Strips any of a set of characters from the end of a String.

        A null input String returns null. An empty string ("") input returns the empty string.

        If the stripChars String is null, whitespace is stripped as defined by Character.isWhitespace(char). 

         StringUtils.stripEnd(null, *)          = null
 StringUtils.stripEnd("", *)            = ""
 StringUtils.stripEnd("abc", "")        = "abc"
 StringUtils.stripEnd("abc", null)      = "abc"
 StringUtils.stripEnd("  abc", null)    = "  abc"
 StringUtils.stripEnd("abc  ", null)    = "abc"
 StringUtils.stripEnd(" abc ", null)    = " abc"
 StringUtils.stripEnd("  abcyx", "xyz") = "  abc"
 StringUtils.stripEnd("120.00", ".0")   = "12"
        Parameters:
        str - the String to remove characters from, may be null
        stripChars - the set of characters to remove, null treated as whitespace
        Returns:
        the stripped String, null if null String input
