StealthBot News Retriever

[Joe[x86]]

When StealthBot starts up, it displays some news about whats been going on latley on the SB world. I wrote a small Java program to retreive that information, and display it to the console. Stealth uses \n in his PHP file to make a new line, and I tried replacing that with \r\n to make a new line, but it doesn't seem to be working. Any suggestions? Heres my code.

           BufferedReader in = new BufferedReader(new InputStreamReader(sckSBNews.getInputStream()));
           BufferedWriter out = new BufferedWriter(new OutputStreamWriter(sckSBNews.getOutputStream()));
           out.write("GET /getver.php HTTP/1.0" + "\r\n" + "Host: www.stealthbot.net" + "\r\n" + "\r\n");
           out.flush();
           while ((line = in.readLine()) != null)
               parseNews(in.readLine());
           sckSBNews.close();

           data2 = data2.replaceAll("ÿcb", "");  // remove any bold flags
           data = data2.split("\n");             // split at new lines
           for(int i = 0; i < data.length; i++) { System.out.println(data[i]); }

If you need to split at \n or \r\n, use BufferedReader.readLine().  It looks after that for you.

[Joe[x86]]

Thanks.

Also, try not to throw away useful information.  You're only processing even numbered lines.  Finally, consider not doing concatenation of several adjacent string constants; just write them as one.  It works the same, but concatenating them like that looks a bit silly.

Good point

Haha, I saw that but opted to ignore it.

Woah, huh?

After some random changes I put to the test, I've managed to pump out this.

I'm going to keep working on it, and parsing the \n's still seems impossible. Also, BufferReader.readLine() doesn't seem to fix that.

Should I just input the 4th line of each thing the server sends back, or is there a more professional way to do it?

[dxoigmn]

Here is something I put together real quick. It uses the built in classes so one doesn't actually have to parse through the http headers and such. I didn't do any parsing of the actual data (news) since I figured you should be able to do that. This is pretty easy to follow if you have the SDK in front of you.

Mind linking me to the SDK? Looks good at a quick glance. I'll test it later today after I've gone to bed. Erm, had a nap?

Thanks MyndFyre.

I'm going to work on this right now waiting for Blizzy to get their effing servers back up.

Excellent. You men happen to be my heroes of the day!

In java, for a string's split method, it takes a regular expression, NOT a character(s) to split on like in Visual Basic. So what you probably need to do is escape the character (in this case the pipe, |) since the pipe is a special character in regular expressions.

Alternatively, you could use Java's StringTokenizer class, which can take one or more characters as delimiters.  You then run through it in the following manner:
