Answer 1

The error in this code is that the variable b is declared inside the if statement, but it is used outside of it. The variable b should be declared outside of the if statement.

Answer 2

b does not have value assigned to.

What input do you expect? what output do you expect?

Answer 3

Did you read when you get some error, what output in console???

error: variable might not have been Intialized.

Learn read first.

Answer 4

I think you need to initialize the int b

So replace int s,b; with int a,b = 0;

Answer 5

bro also you can't do like
int num1 = sc.nextInt() or
int num2 = sc.nextInt()

the correct way is to do like this:
int num1,num2;
num1 = sc.nextInt()
num2 = sc.nextInt()

>>>Remember this is not python or ruby
