You cannot construct an array with a declared length AND a static initialiser. It must be either one or the other.
change inputs[0][0] = new int[14]{1,1,-1,-1,-1,1,-1,-1,1,-1,-1,-1,1,1};
to inputs[0][0] = new int[]{1,1,-1,-1,-1,1,-1,-1,1,-1,-1,-1,1,1};
- the length of the new array is implicit because you are explicitly initialising the array with 14 elements.
