    <p><strong>A program that simply moves array elements.</strong></p> <p>Two variables: <code>userInputVariable</code> and <code>blankSpaceVariable</code>.</p> <p>I have a 2D array named table. Defined as <code>table[userInputVariable + 1][6]</code></p> <p>I am printing out this array in a table format, and the far left column is numbered by whatever number the user entered at the beginning of the program.</p> <p>I then ask the user where they would like to enter a blank space within the array. This blank space acts like a divider for all the other information in the array.</p> <p>For example, if the user enters 10 at the start for the <code>userInputVariable</code>, and then enters 5 for the blank space. Once printed, the numbers should go like this:</p> <p>1, 2, 3, 4, --, 5, 6, 7, 8, 9, 10.</p> <p>My plan has been to create a for loop and try to move all the numbers in the array back a position starting from the blank space variable.</p> <p>What I currently have, but does not work:</p> <pre><code>for (int i = blankSpaceVariable; i &lt; table.length - 1; i++) { table[i] = table[i + 1]; } table[blankSpaceVariable] = "--"; </code></pre> <p>With my current code, the numbers go like this:</p> <p>1, 2, 3, 4, 6, 7, 8, 9, 10</p> <p>Tried completing this a few different ways also, but the other info within my 2D array didn't move with the numbers. So I thought that this approach can hopefully move all the info within my 2D array down, and make way for a blank section.</p> <p>All help is greatly appreciated!</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.
