title: Java - 2D array checking diagonal number board
body: <p>Currently I'm working on a program that generates random 0's and 1's in a 8x8 2D array board. What I have to do is check whether or not if all the numbers on the diagonal are the same (starting from the corners, not just any diagonals).</p>
  <p>example:</p>
  <pre><code>int[][] array = {
      {0, 0, 0, 0, 0, 0, 0, 1},
      {0, 0, 1, 0, 1, 0, 1, 0},
      {0, 0, 0, 0, 1, 1, 1, 0},
      {0, 0, 0, 0, 1, 1, 1, 0},
      {0, 0, 1, 1, 0, 1, 1, 0},
      {0, 0, 1, 0, 0, 0, 1, 0},
      {0, 1, 0, 0, 0, 0, 0, 0},
      {1, 0, 0, 1, 1, 1, 1, 0}
  };
  </code></pre>
  <p>So if by chance all the numbers starting from the top left corner (0,0),(1,1)...(7,7) are all either 0's or 1's then I have to output to the scanner indicating that &quot;There is a major diagonal of 0&quot; (from the example above).</p>
  <p>Also from this example, we can see that from the top-right, the number &quot;1&quot; is repeated diagonally towards the bottom left, then I also have to display &quot;There is a minor diagonal of 1&quot;.</p>
  <p>So far I have figured out how to generate and input the numbers into the array, but I don't know how to check. This is what I have so far:</p>
  <pre><code>public class JavaTest{
  // Main method
  public static void main(String[] args) {
  
      int[][] array = {
          {0, 0, 0, 0, 0, 0, 0, 1},
          {0, 0, 1, 0, 1, 0, 1, 0},
          {0, 0, 0, 0, 1, 1, 1, 0},
          {0, 0, 0, 0, 1, 1, 1, 0},
          {0, 0, 1, 1, 0, 1, 1, 0},
          {0, 0, 1, 0, 0, 0, 1, 0},
          {0, 1, 0, 0, 0, 0, 0, 0},
          {1, 0, 0, 1, 1, 1, 1, 0}
      };
  
      // Print array numbers
      for (int i = 0; i &lt; array.length; i++) {
          for (int j = 0; j &lt; array[i].length; j++)
              System.out.print(array[i][j] + &quot; &quot;);
          System.out.println();
      }
      // Print checkers
  
      checkMajorDiagonal(array);
  }
  // Check major diagonal 
  public static void checkMajorDiagonal(int array[][]) {
      int majDiag;
      boolean isMatching = true;
      int row = 0;
      for(row = 0; row &lt; array.length; row++){
          majDiag = row;
          if(array[row][row] != array[row+1][row+1]){
              isMatching = false;
              break;
          }
      }
      //If all elements matched print output
      if(isMatching)  
          System.out.println(&quot;Major diagonal is all &quot; + array[row][row]);
      }
  }
  </code></pre>
  <p>Though what I have so far is not working as I want it to be as there is an error, and I still have to do the minor diagonal. Thanks in advance.</p>
