[Java] read and write a file

**mickey** · 22nd June 2008, 03:03

Hi,
I have one problem; I must read a html like this;

Qt Code:

Switch view

<html>
<body>
 Hello
</body>
</html>

<html>
<body>
 Hello
</body>
</html>

To copy to clipboard, switch view to plain text mode

I read this in a string (correct?) and after I have to do some changes to it and write it on disk but in this way:

Qt Code:

Switch view

<html>\n<body> ........

<html>\n<body> ........

To copy to clipboard, switch view to plain text mode

There, there's the '\n' because in the original file <body> was in another line of <html>
How can I do this? This my code for read and write:

Qt Code:

Switch view

File fin = new File(FILE_NAME); 	
			FileReader in = new FileReader(fin);			
			istream =  new BufferedReader( in );			    								
			String line = null;
 
			while ( (line = istream.readLine()) != null  ) {
				//System.out.println(line);
				sb.append(line);
			}
                        // here do changes on the sb
                        String text = sb.toString();
			FileWriter fw = new FileWriter(new File ("out.txt") );	
			out = new PrintWriter(fw);  
			out.println(text);

File fin = new File(FILE_NAME); 	
			FileReader in = new FileReader(fin);			
			istream =  new BufferedReader( in );			    								
			String line = null;
			
			while ( (line = istream.readLine()) != null  ) {
				//System.out.println(line);
				sb.append(line);
			}
                        // here do changes on the sb
                        String text = sb.toString();
			FileWriter fw = new FileWriter(new File ("out.txt") );	
			out = new PrintWriter(fw);  
			out.println(text);

To copy to clipboard, switch view to plain text mode

Thanks,
