                int a = 89;
                int b = 8;

                String ab = String.valueOf(a) + String.valueOf(b);
                String ba = String.valueOf(b) + String.valueOf(a);

                int abInt = Integer.parseInt(ab);
                int baInt = Integer.parseInt(ba);

                int answer = abInt >= baInt ? abInt : baInt;
        }
