Hi Friend,

Try the following code:

import java.io.*;
class PrintNumbers{
    public static void main(String[] args) throws Exception{
        FileWriter fstream = new FileWriter(new File("numbers.txt"),true);
        BufferedWriter out = new BufferedWriter(fstream);
        int N=10000;
        for(int i=1;i<=N;i++){
        System.out.println(i);
        out.write(Integer.toString(i));
        out.newLine();
        }
        out.close();
        }
}

Thanks
