If you just want to write it out so you ran read it back in again
without looking at it, you can use serialisation.

Good suggestion but with serialisation you can't open the text file in
notepad and look at it in text file.

But it was faster ..

import java.io.*;
import java.math.*;
import java.util.*;

public class BigNumber {

    public static void main(String[] args) throws Exception
   {
       BigInteger bigInteger = new BigInteger (10000000, new
Random());
             ObjectOutputStream outStr = new ObjectOutputStream
              (new FileOutputStream("number.txt"));
             outStr.writeObject(bigInteger);
             outStr.flush();
             outStr.close();
    }
}

This same thing didn't work with bufferedstream due very slow toString

The question still is how can I write the number (instead of object)
to file without toString...
