    • replace

      public static String replace​(String text, String searchString, String replacement)
      The modified implementation is based on StringUtils#replace(String text, String searchString, String replacement, int max), Apache commons-lang3-3.6

      Replaces all occurrences of a String within another String.

      A null reference passed to this method is a no-op.

       StringUtils.replace(null, *, *)        = null
       StringUtils.replace("", *, *)          = ""
       StringUtils.replace("any", null, *)    = "any"
       StringUtils.replace("any", *, null)    = "any"
       StringUtils.replace("any", "", *)      = "any"
       StringUtils.replace("aba", "a", null)  = "aba"
       StringUtils.replace("aba", "a", "")    = "b"
       StringUtils.replace("aba", "a", "z")   = "zbz"
       
      Parameters:
      text - text to search and replace in, may be null
      searchString - the String to search for, may be null
      replacement - the String to replace it with, may be null
      Returns:
      the text with any replacements processed, null if null String input
    • isEmpty

      public static boolean isEmpty​(CharSequence cs)
      Copied from Apache commons-lang3-3.6

      Checks if a CharSequence is empty ("") or null.

       StringUtils.isEmpty(null)      = true
       StringUtils.isEmpty("")        = true
       StringUtils.isEmpty(" ")       = false
       StringUtils.isEmpty("bob")     = false
       StringUtils.isEmpty("  bob  ") = false
       

      NOTE: This method changed in Lang version 2.0. It no longer trims the CharSequence. That functionality is available in isBlank().

      Parameters:
      cs - the CharSequence to check, may be null
      Returns:
      true if the CharSequence is empty or null
