java code:

  
import java.io.*;

public class ConvertToBin {

public static void main(String[] args) {

String inFile ="numbers.txt";
String ouFile ="binaryNumber.dat";


try (
InputStream inputStream = new FileInputStream(inFile);
OutputStream outputStream = new FileOutputStream(ouFile);
) {

long fileSize = new File(inFile).length();

byte[] Bytes = new byte[(int) fileSize];

inputStream.read(Bytes);

outputStream.write(Bytes);

} catch (IOException ex) {
ex.printStackTrace();
}
}
}
