    <p>The detailed flowchart of full uncaught exception handling is given here: <a href="http://www.javamex.com/tutorials/exceptions/exceptions_uncaught_handler.shtml" rel="nofollow noreferrer">How uncaught exceptions are handled in Java</a>.</p> <blockquote> <p>When an uncaught exception occurs, the JVM does the following:</p> <ul> <li>it calls a special private method, <code>dispatchUncaughtException()</code>, on the <code>Thread</code> class in which the exception occurs; <ul> <li>[...which] calls the thread's <code>getUncaughtExceptionHandler()</code> method to find out the appropriate uncaught exception handler to use. Normally, this will actually be the thread's parent <code>ThreadGroup</code>, whose <code>handleException()</code> method by default will print the stack trace. </li> </ul></li> <li>it then <em>terminates</em> the thread in which the exception occurred. </li> </ul> </blockquote> <p>Therefore you can, if you wish to, create your own custom uncaught exception handler.</p> <p>It should also be noted that while <code>main</code> is commonly used as a Java application entry point, the method is just like any other methods in that it <em>can</em> also be called from other contexts (e.g. other <code>main</code> methods, or even itself recursively!). In that case, the caller can catch exceptions thrown.</p> <pre><code>public class SelfCatch { public static void main(String args[]) throws Exception { if (args == null) throw new Exception("Hi there!"); try { main(null); } catch (Exception e) { System.out.println("Caught: " + e); } System.out.println("Exiting..."); } } </code></pre> <p>Output:</p> <pre><code>Caught: java.lang.Exception: Hi there! Exiting... </code></pre>

    1. CO"The Java runtime catches any uncaught ..." - I believe that this only applies to the thread running "main". By default (i.e. unless something sets an uncaught exception handler) other application-created threads will not report uncaught exceptions.

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.
