        try {
  
            // Create a PrintWriter instance
            PrintWriter printr
                = new PrintWriter(System.out);
  
            // Print the double value '4.5'
            // to this stream using println() method
            // This will put the doubleValue in the
            // stream till it is printed on the console
            printr.println(4.5);
  
            printr.flush();
        }
        catch (Exception e) {
