Answer 1

import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Scanner;

public class FileHandling {
   public static void main(String[] args) throws IOException {
       // check if File exists or not
       Scanner in = null;
       in = new Scanner(new File("number.txt"));
       int n;
       FileOutputStream fos = null;
       BufferedOutputStream writer = new BufferedOutputStream(fos);
       fos = new FileOutputStream("binaryNumber.dat");
       writer = new BufferedOutputStream(fos);
       // read from Scanner till the end of file
       while (in.hasNextInt()) {
           n = in.nextInt();
           writer.write(Integer.toBinaryString(n).getBytes());
           writer.write(" ".getBytes());
       }
       writer.flush();

       // close the file
       in.close();
       writer.close();
   }
