title: Where to download the java.util.*, java.io.* classes?
body: <p>I managed to download files for a java game called "Robobmbo". But I have run into some problems.  Most of the classes have imported other classes like <code>java.net.URLConnection</code>. But I have no idea where to find these files. Can anyone tell me where I can download: <code>java.net.*</code>, <code>java.io.*</code>, etcetera. ?</p>
  
  <p>The example below is from the MusicPlayer.class. Its supposed to play a module music track in the game. I am having a hard time finding this module. I believe the link to the module is in <code>URLConnection</code> or <code>URL</code>. How do I open the <code>URLConnection</code> class file?</p>
  
  <pre><code>package game;
  
  import java.io.BufferedInputStream;
  import java.net.URL;
  import java.net.URLConnection;
  import java.util.Hashtable;
  import java.util.zip.ZipInputStream;
  import litecom.Trace;
  import litecom.modplayer.Mod;
  import litecom.modplayer.ModPlayer;
  </code></pre>
  
  <p>I downloaded Eclipse, opened it, then tried opening the class file but it failed. I searched the internet and found that you should go to <code>preference &gt; general editor</code> and <code>Class File Editor</code> as the default. But there is no class editor in the list :(. What do I do?</p>
