//Create a file with a specified name and file extension.
File file = new File("mahendra.txt");
// Create a output stream and write specified bytes in file.
FileOutputStream objFStream = new FileOutputStream(file);
CloseFilterOutputStream obj=new CloseFilterOutputStream(objFStream);
obj.write(byteArray1);
// create a file input stream to read content of the file.
InputStream in = new FileInputStream(file);
System.out.print("Content of the file : ");
for (int c = in.read(); c != -1; c = in.read()) {
System.out.print((char) c);
