title: Which protocol does Java's Socket use?
body: <p>I'm getting started with Java's <code>Socket</code> and <code>SocketServer</code> classes.</p>
  
  <p>As mentioned above I would like to know which protocol (or however it is called) the Socket classes are using to communicate by default.</p>
  
  <p>It is probably TCP, but I couldn't find anything specific, probably I'm overlooking something.</p>
