Can anybody tell me what's wrong with this?

    I'm not sure how this is incorrect, it's not identical to the solution in terms of syntax but it should have the same functionality:

            int length = 1;
            int prev = nums[0];
            for (int i=1; i < nums.length; i++){
                if (nums[i] != prev){
                    prev = nums[i];
                    length++;
                }
            }
          return length;
        }
