    • trim

      public static String lowerCase(String str)
      Converts a given String to lower case with Locale.ENGLISH
      Parameters:
      str - the string to be converted to lower case
      Returns:
      the lower case of string, or itself if string is null/empty

    • upperCase

      public static String upperCase(String str)
      Converts a given String to upper case with Locale.ENGLISH
      Parameters:
      str - the string to be converted to upper case
      Returns:
      the upper case of string, or itself if string is null/empty

    • compare

      public static int compare(String str1, String str2)
      Compare two strings with Locale.ENGLISH This method is preferred over String.compareTo() method.
      Parameters:
      str1 - String 1
      str2 - String 2
      Returns:
      negative integer if str1 lexicographically precedes str2 positive integer if str1 lexicographically follows str2 0 if both strings are equal
      Throws:
      IllegalArgumentException - throws exception if both or either of the strings is null

    • appendCompactedString

      public static void appendCompactedString(StringBuilder destination, String source)
      This method appends a string to a string builder and collapses contiguous white space is a single space. This is equivalent to: destination.append(source.replaceAll("\\s+", " ")) but does not create a Pattern object that needs to compile the match string; it also prevents us from having to make a Matcher object as well.

    • beginsWithIgnoreCase

      public static boolean beginsWithIgnoreCase(String data, String seq)
      Performs a case insensitive comparison and returns true if the data begins with the given sequence.
