  in unicon/icon it would be

  procedure StringSplit(str)

      #
      # define a local to hold an initial empty list 
      #
      local l := list()
  
      #
      # if the length of the string is odd then concatenate an "_" character
      #
      str ||:= ((*str % 2 = 1) & "_")
      #
      # scan the string and put each two characters onto the end of the list
      # created above, fail when you reach the end of the string
      #
      str ? while put(l, move(2))
      #
      # return the list to the calling program
      #
      return l
   end
  

  and for an example string of "this is a string" it will return the list ["th", "is", " i", "s ", "a ", "st", "ri", "ng"]

  and for an example string of "this is a string2" it will return the list ["th", "is", " i", "s ", "a ", "st", "ri", "ng", "2_"]

  Nice and simple compared to the example given in Java.
