What is the output of the second println statement in the main method?

Question

```
public class Foo {
int i;
static int s;

public static void main(String[] args) {
Foo f1 = new Foo();
System.out.println("f1.i is " + f1.i + " f1.s is " + f1.s);
Foo f2 = new Foo();
System.out.println("f2.i is " + f2.i + " f2.s is " + f2.s);
Foo f3 = new Foo();
System.out.println("f3.i is " + f3.i + " f3.s is " + f3.s);
}

public Foo() {
i++;
s++;
}
}
```
a. f2.i is 1 f2.s is 1
b. f2.i is 1 f2.s is 2
c. f2.i is 2 f2.s is 2
d. f2.i is 2 f2.s is 1

Answer 1

b. f2.i is 1 f2.s is 2
i is an instance variable and s is static, shared by all objects of the Foo class.
