Writing Constructors for Subclasses

AP Computer Science A· difficulty 2/5

public class A {
    public A() { System.out.print("A "); }
}
public class B extends A {
    public B() { System.out.print("B "); }
}
new B();

What is printed when <code> new B() </code> runs?

Explanation

Every subclass constructor implicitly calls <code> super() </code> first. So <code> A() </code> runs, printing "A ", then <code> B() </code> prints "B ".
