Body
Before varargs a method that took an arbitrary number of values required you to create an array put the values into the array prior to invoking the method. Example here is how the MessageFormat class to format a message used to look: <pre><code>Object[] arguments = { new Integer(7), new Date(), "a disturbance in the Force" }; String result = MessageFormat.format( "At {1,time} on {1,date}, there was {2} on planet " + "{0,number,integer}.", arguments); </code></pre> It is still true that multiple arguments must be passed in an array, but the varargs feature automates and hides the process. Furthermore, it is upward compatible with preexisting APIs. So, for example, the MessageFormat.format method now has this declaration: <pre><code>public static String format(String pattern, Object... arguments); </code></pre> The three periods after the final parameter's type indicate that the final argument may be passed as an array or as a sequence of arguments. Varargs can be used only in the final argument position. Given the new varargs declaration for MessageFormat.format, the above invocation may be replaced by the following shorter and sweeter invocation: <pre><code>String result = MessageFormat.format( "At {1,time} on {1,date}, there was {2} on planet " + "{0,number,integer}.", 7, new Date(), "a disturbance in the Force"); </code></pre> So when should you use varargs? As a client, you should take advantage of them whenever the API offers them. Important uses in core APIs include reflection, message formatting, and the new printf facility. As an API designer, you should use them sparingly, only when the benefit is truly compelling. Generally speaking, you should not overload a varargs method, or it will be difficult for programmers to figure out which overloading gets called.

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.
