BigInteger x = new BigInteger ("530500452766");
String s = x.toString(); // valid character data
try {
byte [] byteArray = s.getBytes("UTF8");
String ns = new String(byteArray, "UTF8"); // ns prints as "530500452766"
BigInteger x1 = new BigInteger(ns); // construct the original BigInteger

Do not try to convert the String object to a byte array to obtain the original BigInteger. Character encoded data may yield a byte array which, when converted to a BigInteger, results in a completely different value.
