Connecting otan IRC server

Well so firstly I have made a class so the irc functions are easier to use so here it is.

import java.io.BufferedReader;

import java.io.BufferedWriter;

import java.io.IOException;

import java.io.InputStreamReader;

import java.io.OutputStreamWriter;

/**

public class IRC {

public static void pass(String pass) {

sendRawData((new StringBuilder("PASS ")).append(pass).toString());

}

public static void nick(String nick) {

sendRawData((new StringBuilder("NICK ")).append(nick).toString());

}

public static void user(String nick, String hostname, String servername, String realname) {

sendRawData((new StringBuilder("USER ")).append(nick).append(" ").append(hostname).append(" ").append(servername).append(" ").append(realname).toString());

}

public static void quit(String message) {

sendRawData((new StringBuilder("QUIT :")).append(message).toString());

}

public static void join(String channel) {

sendRawData((new StringBuilder("JOIN ")).append(channel).toString());

}

public static void join(String channel, String password) {

sendRawData((new StringBuilder("JOIN ")).append(channel).append(" ").append(password).toString());

}

public static void part(String channel) {

sendRawData((new StringBuilder("PART ")).append(channel).toString());

}

public static void sendMessage(String channel, String message) {

sendRawData((new StringBuilder("PRIVMSG ")).append(channel).append(" :").append(message).toString());

}

public static String getChannel(String line) {

if (line.indexOf("#") != -1 && line.lastIndexOf(":") != -1 && line.indexOf("PRIVMSG") != -1 && line.indexOf("#") <>

return line.substring(line.indexOf("#"), line.lastIndexOf(" :")).replaceAll(" ", "");

}

if (line.indexOf("PRIVMSG") != -1) {

return line.substring(1, line.indexOf("!"));

} else {

return "null";

}

}

public static String getMessage(String line) {

if (line.lastIndexOf(":") != -1) {

return line.substring(line.lastIndexOf(" :") + 2);

} else {

return null;

}

}

public static String getNick(String line) {

try {

return line.substring(1, line.indexOf("!"));

} catch (Exception e) {

}

return null;

}

public static String readLine() {

try {

BufferedReader reader = new BufferedReader(new InputStreamReader(Main.in));

return reader.readLine();

} catch (IOException ioe) {

return "null";

}

}

public static void sendRawData(String line) {

try {

BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(Main.out));

writer.write((new StringBuilder(String.valueOf(line))).append("\n").toString());

writer.flush();

} catch (IOException ioe) {

}

}

}

Firstly you need to set your nick, to do that just use this.

IRC.nick("Cascade");

An IRC server normally requires you to register so then you would use this command.

IRC.user("Cascade", "null", "null", System.getProperty("user.name"));

Now your a user on the IRC server, now you can join channels with.

IRC.join("#test");

But you have all the commands now you need to setup a while loop to read the data and send pong replys to the server so here is how to do that.

while (true) {

String line = IRC.readLine();

if (line != null) {

if (line.startsWith("PING")) {

IRC.sendRawData(line.replace("PING", "PONG"));

}

}

}

And now your connected to an IRC server, you can make use of the other methods in the IRC class and hopefully this will have taught you something.
