}
public A(int i){
this();
System.out.println(i);
}
}
class B extends A{
public B(){
System.out.println("B");
}
public B(int i){
this();
System.out.println(i+3);
}
}
public class Test{
public static void main (String[] args){
new B(5);
}
}
class A{
public A(){
System.out.println("A");
}
public A(int i){
this();
System.out.println(i);
}
}
class B extends A{
public B(){
System.out.println("B");
}
public B(int i){
this();
System.out.println(i+3);
}
}
public class Test{
public static void main (String[] args){
new B(5);
}
}A. A B 8
B. A 5 B 8
C. A B 5
D. B 8 A 5
E. None of these
