public class BufferedWriterDemo {
   public static void main(String[] args) throws IOException {
      StringWriter sw =null;
      BufferedWriter bw = null;
      String s = "Hello World!!";
            
      try {
         // create new string writer
         sw = new StringWriter();
         
         // create new buffered writer
         bw = new BufferedWriter(sw);
         
         // write string sequence to buffered writer
         bw.write(s, 0, 5);
   
         // write new line to the buffered writer
         bw.newLine();
         
         // write the next string sequence to buffered writer
         bw.write(s, 6, s.length()-6);
         
         // releases all bytes to the underlying stream
         bw.flush();

         // print
         System.out.print(sw.getBuffer());
         
      } catch(Exception e) {
         // if any I/O error occurs
         e.printStackTrace();
      } finally {
         // releases system resources from the streams
         if(sw!=null)
            sw.close();
         if(bw!=null)
            bw.close();
