//10. Analyze the following code:

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

class A {
  int i = 7;
  public A() {
    setI(20);
    System.out.println("i from A is " + i);
  }

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

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

  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".
//Key:d
