A Java program that writes Fibonacci numbers into a text file

import java.math.BigInteger;
import java.io.*;


public class FibonacciText {

  public static void main(String[] args) {

    try {
      FileOutputStream   fout = new FileOutputStream("fibonacci.txt");
      OutputStreamWriter out  = new OutputStreamWriter(fout, "8859_1");

      BigInteger low  = BigInteger.ZERO;
      BigInteger high = BigInteger.ONE;

      for (int i = 0; i <= 25; i++) {
        out.write(low.toString() + "\r\n");
        BigInteger temp = high;
        high = high.add(low);
        low = temp;
      }

      out.close();
    }
    catch (IOException e) {
      System.err.println(e);
    }
