I need my array elements to be dynamically initialized but i can't get my simple 2d array to hold anything...</p> <p>Here is my whole code file...</p> <pre><code>import javax.swing.*; import java.awt.*; public class ColoredGrid extends JPanel { final int ROWS = 2; final int COLS = 2; int vLines[][] = new int[ROWS][COLS]; vLines[0][0] = (int)(1*.33); vLines[0][1] = (int)(1*.33); vLines[1][0] = (int)(1*.33); vLines[1][1] = (int)(1*.33); public ColoredGrid() { } protected void paintComponent(Graphics g){ super.paintComponent(g); } } </code></pre>

    1. COYou probably have a syntax error elsewhere, since the code you've shown us looks fine.

    2. COThe lines "vLines[0][0] = (int)(1*.33);" etc are NOT allowed in the body of the class. They should either be in an initialization block {} or the constructor.

    3. COIncidentally, now that your code works, it's still not actually doing anything useful. `(int)(1*.33)` is just `0`, which is what the elements would be initialized to anyway.

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.
