    <p>I'm playing around with some code katas and trying to get a better understanding of java generics at the same time. I've got this little method that prints arrays like I like to see them and I have a couple of helper methods which accept an array of 'things' and an index and returns the array of the 'things' above or below the index (it's a binary search algorithm). </p> <p>Two questions, </p> <p>#1 Can i avoid the cast to T in splitBottom and splitTop? It doesn't feel right, or I'm going about this the wrong way (don't tell me to use python or something .. ;) )</p> <p>#2 Do I have to write seperate methods to deal with primitive arrays or is there a better solution?</p> <pre><code>public class Util { public static &lt;T&gt; void print(T[] array) { System.out.print("{"); for (int i = 0; i &lt; array.length; i++) { System.out.print(array[i]); if (i &lt; array.length - 1) { System.out.print(", "); } } System.out.println("}"); } public static &lt;T&gt; T[] splitTop(T[] array, int index) { Object[] result = new Object[array.length - index - 1]; System.arraycopy(array, index + 1, result, 0, result.length); return (T[]) result; } public static &lt;T&gt; T[] splitBottom(T[] array, int index) { Object[] result = new Object[index]; System.arraycopy(array, 0, result, 0, index); return (T[]) result; } public static void main(String[] args) { Integer[] integerArray = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}; print(integerArray); print(splitBottom(integerArray, 3)); print(splitTop(integerArray, 3)); String[] stringArray = {"one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten"}; print(stringArray); print(splitBottom(stringArray, 3)); print(splitTop(stringArray, 3)); int[] intArray = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}; // ??? } } </code></pre>

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.
