title: Writing a Java program in Xcode
body: <p>I am trying to begin writing a Java program in <code>Xcode 4.4</code> but, At the moment, I am stuck with the file extension <code>.cpp</code>, which I believe is for C++. Can some please tell me how to set up a <code>.java</code> file (or project, or whatever the term is)...? I am extremely new to programming, and to Xcode, so please keep all instructions /very/ simple. </p>
