AP Computer Science A· difficulty 4/5

public class A {
    public String name() { return "A"; }
    public String label() { return "[" + name() + "]"; }
}
public class B extends A {
    public String name() { return "B"; }
}
System.out.println(new B().label());

What is printed?

A
$[B]$
check_circle
B
$[A]$
C
$[]$
D
$Compile-time error$

Explanation

<code> label() </code> is inherited from A but calls <code> name() </code> on <code> this </code> . Since this is a B, dynamic dispatch picks B.name().
