    <p>In the following code snippet, presumably it appears that it should issue some compilation error but it doesn't:</p> <pre><code>class Outer { public static class Inner { static String obj = "Inner"; } static Optional Inner = new Optional(); //The (inner) class name and the object name are same. } class Optional { String obj = "Optional"; } public class Main { public static void main(String[] args) { System.out.println(Outer.Inner.obj); //Refers to the string inside the optional class } } </code></pre> <p>The class <code>Outer</code> has a static class inside it named <code>Inner</code>. Additionally, it declares an object (static) of the class <code>Optional</code> (<code>static Optional Inner = new Optional();</code>)</p> <p>This object and the class names (inside the class <code>Outer</code>) are same which is <code>Inner</code>. The program displays <code>Optional</code>. The only expression <code>Outer.Inner.obj</code> within <code>main()</code> is expected to display <code>Inner</code> but it doesn't. The actual output is however <code>Optional</code> which is the case of the <code>Optional</code> class. </p> <p>One way to display <code>Inner</code> is by changing the object name to something else.</p> <pre><code>static Optional Inner1 = new Optional(); </code></pre> <p>From the output it displays, it appears that the object name (or a variable) is chosen over a type name (the class <code>Inner</code>) because they have the same name. What exact case is applied here?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
