Multi Dimensional Arrays and nextBoolean

Hi,
I'm trying to solve a problem and have come to the stage of tearing my hair out! Basically I want to create a java program that produces a console display like so.
x0xx0
0x00x
0xxx0
xxx00
0000x
The rows and columns must be randomly filled.
I believe that one needs to use a two dimensional array to achieve this problem and have come across/ modified the following code out of two java problems.
THIS PROGRAM BASICALLY PRINTS OUT AN ARRAY OF 5 x 5 numbers.
public class ArrayOfArraysDemo2 { public static void main(String[] args) { int[][] aMatrix = new int[5][5]; //populate matrix for (int i = 0; i < aMatrix.length; i++) { aMatrix[i] = new int[5];//create sub-array for (int j = 0; j < aMatrix[i].length; j++) { aMatrix[i][j] = i + j; } } //print matrix for (int i = 0; i < aMatrix.length; i++) { for (int j = 0; j < aMatrix[i].length; j++) { System.out.print((aMatrix[i][j] +1) + " "); } System.out.println(); } } }
THE NEXT PROGRAM I CAME ACROSS USES nextBoolean TO ASSIGN RANDOM LETTERS TO A GRID AND THEN REPEATS THE RANDOM GRID A NUMBER OF TIMES.
import java.util.Random; class RandomValuesTrue { public static void main(String args[]) { Random r = new Random(); int h = 0; while(h < 5){ for(int i = 0; i < bVals.length; i++){ for(int j = 0; j < bVals[i].length; j++){ bVals[i][j] = i + j; } } for(int i = 0; i < bVals.length; i++){ for(int j = 0; j < bVals[i].length;j++){ System.out.println(r.nextBoolean() ? "1" : "0"); } System.out.println(" "); h++; } } } }
The RandomValuesTrue.java program is nearly what I want, regrettably it only prints out one column to the console.
Please, please, please can someone help me two work out how to generate a random grid using the code I've created in RandomValuesTrue and stop me from becoming prematurely bald?
Thanks for your help.

Another way, maybe.
class Testing { public Testing() { String[] what = {"x","O"}; for(int i = 0; i < 25; i++) { if(i % 5 == 0)System.out.println(); System.out.print(what[(int)(Math.random()*2)]); } System.exit(0); } public static void main(String[] args){new Testing();} }
