    <blockquote> <pre><code>/** * Clones the provided array * * @param src * @return a new clone of the provided array */ public static int[][] cloneArray(int[][] src) { int length = src.length; int[][] target = new int[length][src[0].length]; for (int i = 0; i &lt; length; i++) { System.arraycopy(src[i], 0, target[i], 0, src[i].length); } return target; } </code></pre> </blockquote> <p>Is it possible to modify this code to support <strong>n-dimensional arrays of Objects</strong>?</p> <p>You would need to support arbitrary lengths of arrays and check if the src and destination have the same dimensions, <s>and you would also need to copy each element of each array <em>recursively</em>, in case the Object was also an array.</s></p> <p>It's been a while since I posted this, but I found a <strong><a href="https://stackoverflow.com/questions/4770926/java-n-dimensional-arrays">nice example</a></strong> of one way to create an n-dimensional array class. The class takes zero or more integers in the constructor, specifying the respective size of each dimension. The class uses an underlying <em>flat</em> array <code>Object[]</code> and calculates the index of each element using the dimensions and an array of multipliers. (This is how arrays are done in the C programming language.) </p> <p>Copying an instance of <code>NDimensionalArray</code> would be as easy as copying any other 2D array, though you need to assert that each <code>NDimensionalArray</code> object has equal dimensions. This is probably the easiest way to do it, since there is no recursion, and this makes representation and access much simpler.</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.
