    <p>There are a couple of ways to do this. The simplest I can think of is to remove the loops from the <code>populateRandom()</code> function (and maybe name it something else) and call it inside the inner most loop in <code>drawGrid()</code></p> <pre><code>static char[] options = { '*', '$', '@', '+', '!', '&amp;' }; public static void main(String[] args) { System.out .println("How to play: type a row and column index, followed by \n" + "the direction to move it: u (up), r (right), d (down), l (left)"); char[][] grid = new char[8][8]; drawGrid(grid); System.out .println("Enter &lt;row&gt; &lt;column&gt; &lt;direction to move&gt; or q to quit"); // char randomChar = 66; // System.out.println(randomChar); } public static void drawGrid(char[][] grid) { System.out.println("\t1 \t2 \t3 \t4 \t5 \t6 \t7 \t8"); System.out.println(); // Random r = new Random(); for (int row = 0; row &lt; grid.length; row++) { // populateRandom(grid,options); System.out.print((row + 1) + ""); for (int column = 0; column &lt; grid[row].length; column++) { populateRandom(grid[row][column]); } System.out.println(); } System.out.println(); } public static void populateRandom(char grid) { Random randomGenerator = new Random(); int randomIndex = randomGenerator.nextInt(6); grid = options[randomIndex]; System.out.print("\t" + grid); } public static boolean isWithinGrid(int row, int col, String cmd, char[][] grid) { return true; } public static void swap(int row, int col, String cmd, char[][] grid) { } public static boolean updateGrid(char[][] grid, char[] options) { return false; } </code></pre> <p>The problem with what you are doing is that, on console, once you go to a new line, you can't go back and print more stuff on the previous line (actually you can but it's really cumbersome and pointless).</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.
