title: Creating hashmap from json data
body: <p>I am working on a very simple application for a website, just a basic desktop application.</p>
  
  <p>So I've figured out how to grab all of the JSON Data I need, and if possible, I am trying to avoid the use of external libraries to parse the JSON. </p>
  
  <p>Here is what I am doing right now:</p>
  
  <pre><code>package me.thegreengamerhd.TTVPortable;
  
  import java.io.BufferedReader;
  import java.io.IOException;
  import java.io.InputStreamReader;
  import java.net.URL;
  import java.net.URLConnection;
  
  import me.thegreengamerhd.TTVPortable.Utils.Messenger;
  
  
  public class Channel
  {
  URL url;
  String data;
  String[] dataArray;
  
  String name;
  boolean online;
  int viewers;
  int followers;
  
  public Channel(String name)
  {
      this.name = name;
  }
  
  public void update() throws IOException
  {
      // grab all of the JSON data from selected channel, if channel exists
      try
      {
          url = new URL("https://api.twitch.tv/kraken/channels/" + name);
          URLConnection connection = url.openConnection();
          BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
          data = new String(in.readLine());
          in.close();
          // clean up data a little, into an array
          dataArray = data.split(",");
      }
      // channel does not exist, throw exception and close client
      catch (Exception e)
      {
          Messenger.sendErrorMessage("The channel you have specified is invalid or corrupted.", true);
          e.printStackTrace();
          return;
      }
  
      StringBuilder sb = new StringBuilder();
      for (int i = 0; i &lt; dataArray.length; i++)
      {
          sb.append(dataArray[i] + "\n");
      }
  
      System.out.println(sb.toString());
  }
  }
  </code></pre>
  
  <p>So here is what is printed when I enter an example channel (which grabs data correctly)</p>

  <p>Initializing User Interface - JOIN</p>
  
  <p>All of this is correct. Now what I want to do, is to be able to grab, for example the 'mature' tag, and it's value. So when I grab it, it would be like as simple as:</p>
  
  <pre><code>// pseudo code
  if(mature /*this is a boolean */ == true){ // do stuff}
  </code></pre>
  
  <p>So if you don't understand, I need to split away the quotes and semicolon between the values to retrieve a Key, Value.</p>
