    <p>I am populating a list array with lines from a csv file. I have some empty columns and some not. I would like these empty columns to contain "0" if they are empty. The length of the string[] could be 1 to 7. However, I need to return 7 items when all is said and done.</p> <p>My data looks like this: </p> <blockquote> <p>Brenda Mines Snow Pillow,2013-11-26 04:00:00,-2.943,364,59,,</p> </blockquote> <p>or this:</p> <blockquote> <p>Barnes Creek Snow Pillow,2013-11-26 04:00:00,-6.6,344,117,10,12.97</p> </blockquote> <p>or possible other variations missing other columns. </p> <p>How do I always make my final <code>String[] data;</code> have 7 items in it? </p> <pre><code>data[0] through data[6] </code></pre> <p>I have tried an <code>if(data[i] == null){data[i] = "0";}</code> but that doesn't work since my list from the parsed data may not have a length of i and I get a index OB error. </p> <p>I tried creating another array and adding the items in there and then if an item from <code>data[i] was null, data2[i] = "0" else data[i] = data2[i];</code> However, data[i] might not exists... I am just confused on how to make my array always contain 7 items.</p> <p>Any help would be so great. I should add that I have tried to initialize first: String[] data = {"0","0","0","0","0","0","0"} </p> <p><strong>EDIT: I checked to make sure data.length was 7... it was, so what the problem was: <a href="https://stackoverflow.com/questions/9444638/null-vs-empty-string">NULL vs empty string</a> is answered here.</strong></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.
