Question: Three classes are defined as below. public class Person{ private String name; public Person(String n) { name = n; } public String toString() { return

Three classes are defined as below.

public class Person{ private String name; public Person(String n) { name = n; } public String toString() { return name; } } public class Senator extends Person{ private String party; public Senator(String n, String p){ super(n); party = p; } public String toString(){ String init = " (" + party.substring(0,1) +")"; return "Sen. " + super.toString() + init; } } class SenateLeader extends Senator{ private boolean majority; public Senator(String n, String p, boolean m){ super(n, p); majority = m; } }

The following code segment appears in method in a separate class.

ArrayList list = new ArrayList(); Person n = new SenateLeader("Mike Mansfield", "Democratic", true); list.add(n);

Which of the following best describes why this code will not compile correctly?

Objects cannot be added to an empty ArrayList

An object which is initialized as a SenateLeader cannot be added to an ArrayList of Senator type objects

A variable which is declared as a Person cannot be initialized as a SenateLeader

An object which is declared as a Person cannot be added to an ArrayList of Senator type objects

The actual parameters passed to the SenateLeader constructor do not match the signature of this constructor
