Nothing is impossible, even the word impossible says 'i m possible'.

Try using a StringBuffer and then loop through the Strings that you wish to concetnate passing it to the append() method on the StringBuffer.

Give him the code dear.
Okie here u go,
Assuming i have a 100 strings in a String array arr.
StringBuffer stringbuffer = new StringBuffer(200);
for(int i = 0;i < arr.length; i++ )
if(!String.valueOf( arr[i] ).equals("null"))
if(i != 0)stringbuffer.append(",");

stringbuffer.append( arr[i] );
System.out.println( stringbuffer );
Give it a shot dude.Tell me if it doesnt work.Try some R&D okie?? I havent tried compiling and runing the program.
