I also tried using a StringBuffer and it works fine. Thanks Michael & Neil.
String ret = "";
try{
String thisLine = null;
StringBuffer buffer = new StringBuffer( );
BufferedReader myInput = new BufferedReader(new FileReader(fn));
while ((thisLine = myInput.readLine()) != null) {
buffer.append( thisLine );
buffer.append( "\n" );
}
myInput.close();
ret = buffer.toString( );
}
catch (Exception e) {
ret = "Cannot load, exception!";
}
Sincerely,
Ali.
