title: How to concatenate several strings with different format and then split them
body: <p><BR> Hi all.<br>
  I want to concatenate some strings without specified format in java. for example I want to concatenate multiple objects like signature and BigInteger and string, that all of them are converted to string. So i can not use of the specified delimiter because each delimiter may be exist in these strings. how i can concatenate these strings and then split them?<BR>
  thanks all.</p>
