POHow Can I Display a N x N Matrix of Random Numbers in Java?
text
Body
copied!<p>I'm trying to create a matrix of random double numbers. The matrix must be of size n x n and all numbers must be between 1 and 100. I've been trying to sort it out for ages now and I know it must be something so simple (as it usually is).</p> <p>Here is my code:</p> <pre><code>public static void main(String[] args) { PrintRandomGraph(RandomArray(4)); } private static double[] RandomArray(int n) { double[] randomArray = new double[n]; double[][] randomMatrix = new double [n][n]; Random rand = new Random(); rand.setSeed(System.currentTimeMillis()); for (int i = 0; i < n; i++) { Integer r = rand.nextInt()% 100; randomArray[i] = Math.abs(r); for (int j = 0; j < n; j++) { Arrays.fill(randomMatrix, i, i+1, randomArray); } } return randomArray; } private static void PrintRandomGraph(double[] inputArray) { int n = inputArray.length; double[] showArray = new double[n]; double[][] showMatrix = new double [n][n]; for (int j = 0; j < n; j++) { for (int i = 0; i < n; i++) { double r = inputArray[i]; showArray[i] = r; Arrays.fill(showMatrix, i, i+1, showArray); } } System.out.println(Arrays.deepToString(showMatrix)); } </code></pre> <p>When I run the code I get a random array repeated n times like : </p> <blockquote> <p>[[63.0, 97.0, 64.0, 75.0], [63.0, 97.0, 64.0, 75.0], [63.0, 97.0, 64.0, 75.0], [63.0, 97.0, 64.0, 75.0]]</p> </blockquote> <p>I think I need to go back to the top of the for loop and add the new array...? Please help =(</p> <p>Any help is much appreciated. Thank you.</p>
