   <body>
      <c:set var = "string1" value = "This is first String."/>
      <c:set var = "string2" value = "${fn:split(string1, ' ')}" />
      <c:set var = "string3" value = "${fn:join(string2, '-')}" />

      <p>String (3) : ${string3}</p>

      <c:set var = "string4" value = "${fn:split(string3, '-')}" />
      <c:set var = "string5" value = "${fn:join(string4, ' ')}" />

      <p>String (5) : ${string5}</p>
   </body>
</html>

You will receive the following result −

String (3) : This-is-first-String.
String (5) : This is first String.
