Analyze the following code:

Question

```
public class Test {
public static void main(String[] args) {
new B();
}
}

class A {
int i = 7;

public A() {
System.out.println("i from A is " + i);
}

public void setI(int i) {
this.i = 2 * i;
}
}

class B extends A {
public B() {
setI(20);
// System.out.println("i from B is " + i);
}

@Override
public void setI(int i) {
this.i = 3 * i;
}
}
```
a. The constructor of class A is not called.
b. The constructor of class A is called and it displays "i from A is 7".
c. The constructor of class A is called and it displays "i from A is 40".
d. The constructor of class A is called and it displays "i from A is 60".

Answer 1

b. The constructor of class A is called and it displays "i from A is 7".
When invoking new B(), B's superclass A's constructor is invoked first. So it displays i from A is 7.
