I have a problem with control characters in java String. Say i have a code like this
byte[] b = new byte[1024];
DatagramPacket d = new DatagramPacket(b, b.length);
the array b will be initialised with null characters. when the datagram is received, its length is lesser than 1024... and when i convert the byte array to string and write to a file, i get those pesky control characters at the end. Please give me some code that'll replace all the control characters (except may b \n and \t) with something else (say, space).
