/**
 * <h1>The Class Name Myth</h1>
 *
 * <h2>The Final Conclusion</h2>
 * <p>Whether a Java source file compiles depends on the relationship between the
 * class name, the file name, and whether the class is declared <code>public</code>.
 * There are three cases to consider.</p>
 *
 * <ul>
 *   <li>If the class is <code>public</code> and the file name is the same as the
 *       class name, then it works fine.</li>
 *   <li>If the class is <code>public</code> and the file name is different from the
 *       class name, then it throws an error &mdash; the class name and file name
 *       must be the same.</li>
 *   <li>If the class is not <code>public</code> and the file name is different from
 *       the class name, then it still works fine.</li>
 * </ul>
 *
 * <p>The programs demonstrating each case are shown below.</p>
