body: <p>I want to check a multidimensional-array which size is 8x8 if 4 in a row have the same value and then call another Method.<code>IF as a example the positions 0/0, 0/1, 0/2, 0/3 have the value 1</code> then the Method <code>finish(1)</code> gets Called. 'But that should also work on Diagonal like 0/0, 1/1, 2/2, 3/3.'</p>
