  1. PONeed help finding all possible combinations, method almost complete
    text
    copied!<p>I can't seem to get this code to work. What I am doing is populating an array with all possible combinations of 2 digits (each of these digits representing a shape and color, respectively). Then, I am trying to use this array to populate a 2d array in which i create all possible combinations of the elements housed in the previous array. For some reason, my 2d array is filled with all '21' instead of any sort of combination.</p> <p>I can post the rest of the code in the class if needed, but it's rather long. The final loop in this method is just used to print them for testing and will be deleted afterwards.</p> <pre><code>public void combinations() { combinations = new int[numShapes*numColors]; int index = 0; for(int l = 1; l &lt;= numShapes; l++) for(int h = 1; h &lt;= numColors; h++) if(index + 1 != combinations.length + 1) combinations[index++] = (l*10) + h; else break; int[][] combs = new int[(int)Math.pow((numShapes*numColors),numPositions)][numPositions]; //Fills the array with all '21' , fix this int ind = 0; for(int f = 0; f &lt; 16; f++) for(int i = 0; i &lt; numShapes; i++) for(int j = 0; j &lt; numColors; j++) if(ind != combs.length+1){ combs[ind] = new int[]{combinations[numShapes], combinations[numShapes], combinations[numColors]}; ind++; } else break; for(int p = 0; p &lt; 2; p++){ for(int g = 0; g &lt; 3; g++){ System.out.print(testFormat(combs[p][g]/10, combs[p][g]%10) + " "); } System.out.println(); } } </code></pre>
