Question

System.out.println(sum);
}}

8.what is the value of b?
9.what is the value of a;
10. What is the value of sum?

Answer 1

What are your observations?
Jumping into using variables before declaring it..?
No values assinged? How the values come out?

Answer 2

B = ++ b- a and A= (b- a
Sum = a+ B
