		File data = new File("D:\\testout.txt");
		FileOutputStream file = new FileOutputStream(data);
		FilterOutputStream filter = new FilterOutputStream(file);
		String s="Welcome to javaTpoint.";    
		byte b[]=s.getBytes();    
		filter.write(b);   
		filter.flush();
		filter.close();
		file.close();
