        try {
            BufferedOutputStream bos;
            try (FileOutputStream fos = new FileOutputStream(new File(sFileName))) {
                bos = new BufferedOutputStream(fos);
                String s = "Java Programming";
                bos.write(s.getBytes());
                bos.flush();
            }

        } catch (IOException ioe) {

package javaapplication1;

import java.io.DataOutputStream;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;

public class JavaApplication1 {

    public static void main(String[] args) {

        String sFileName = "d://data.txt";
        byte[] bArr = {97, 98, 99, 100, 101};

        try {
            DataOutputStream dos;
            try (FileOutputStream fos = new FileOutputStream(new File(sFileName))) {
                dos = new DataOutputStream(fos);
                for (byte b : bArr) {
                    dos.writeChar(b);
                }
                dos.flush();
