Body
<p>Currently I have the following: </p> <pre><code>public String[] readCancer() { cancers = new String[22]; split = new String[22]; FileInputStream fis; InputStreamReader isr; BufferedReader br = null; String eachCancer; int j = 0; try { fis = new FileInputStream(myData); isr = new InputStreamReader(fis); br = new BufferedReader(isr); input = new Scanner(br); while(input.hasNext() && j < 23) { cancers[j] = input.nextLine().toString(); //cancers[j] = input.nextLine(); split[j] = cancers[j].split(":"); //split[j] = "blah"; this line works j++; } System.out.println(Arrays.toString(split)); } catch (IOException iox) { JOptionPane.showMessageDialog(null, "Problem with file input"); } finally { try { if(br != null) { br.close(); } } catch (IOException iox) { JOptionPane.showMessageDialog(null, "Problem closing the file"); } } return split; //return split[j]; does not work } </code></pre> <p>In my while loop, I keep getting compile errors saying it requires a String but found Stirng[] for split. When I try something simpler, such as split[j] = "blah";, there are no compile errors. I can return cancers perfectly but I need to split by the : delimiter and that seems to be something I cant get my head around. When I try return split[j], then I get another compile error saying it requires a String[] but found String. I've been at this for more than an hour, read through examples in my textbook and tutorials online for using split but it still isn't working. This is the only part of my program that I'm not sure how to do. </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.
