For the base public class Person example provided in the Unit $3$ Revisiting the Employee Class Program tutorial, what if you need to add a subclass for Visitors who have a host employee and are visiting a specific building?

What code segment could implement this subpublic class and create an instance of it called visitor$\_1?$

public class Visitor extends Person$\{$

private String host;

private String areaVisiting;

public Visitor$($String firstName,String lastName,String jobTitle,String host, String areaVisiting$)\{$

super$()$;

this.host $=$ host;

this.areaVisiting $=$ areaVisiting;

$\}$

public String getHost$()\{$

return "Host $"+$ this.host;

$\}$

public void setHost$($String newhost$)\{$

this.host $=$ newhost;

$\}$

public String getArea$()\{$

return "Area Visiting $"+$ this.area$\_$visiting;

$\}$

public void setArea$($ String areaVisiting$)\{$

this.areaVisiting $=$ areaVisiting;

$\}$

$\}$

Visitor visitor$\_1=$ new Visitor$("$John$",$"Doe","Visitor","Jane Doe","Main Building"$)$;

public class Visitor extends Person $\{$

private String host;

private String areaVisiting;

public Visitor$($String firstName,String lastName,String jobTitle,String host, String areaVisiting$)\{$

super$($firstName$,$lastName,jobTitle,host,areaVisiting$)$;

this.host $=$ host;

this.areaVisiting $=$ areaVisiting;

$\}$

public String getHost$()\{$

return "Host $"+$ this.host;

$\}$

public void setHost$($String newhost$)\{$

this.host $=$ newhost;

$\}$

public String getArea$()\{$

return "Area Visiting $"+$ this.area$\_$visiting;

$\}$

public void setArea$($ String areaVisiting$)\{$

this.areaVisiting $=$ areaVisiting;

$\}$

$\}$

Visitor visitor$\_1=$ new Visitor$("$John$",$"Doe","Visitor","Jane Doe","Main Building"$)$;

public class Visitor extends Person $\{$

private String host;

private String areaVisiting;

public Visitor$($String firstName,String lastName,String jobTitle,String host, String areaVisiting$)\{$

$\}$

public String getHost$()\{$

return "Host $"+$ this.host;

public void setHost$($String newhost$)\{$

this.host $=$ newhost;

public String getArea$()\{$

return "Area Visiting $"+$ this.areaVisiting;

$\}$

public void setArea$($ String areaVisiting$)\{$

this.areaVisiting $=$ areaVisiting;

$\}$

$\}$

Visitor visitor$\_1=$ new Visitor$("$John$",$"Doe","Visitor","Jane Doe","Main Building"$)$;

public class Visitor $\{$
