Consider the following class hierarchy:

public final class Shape

$\{$

private String mycolor;

public Shape$($String mycolor$)$

$\{$

$\}$

this.type $=$ mycolor;

public String getColor$()$

$\{$

$\}$

return mycolor;

$\}$

public class Triangle extends Shape

$\{$

public Triangle$($String mycolor$)$

$\{$

$\}$

super$($mycolor$)$;

$\}$

What is wrong with this class hierarchy definition?

It is not possible to use

in the

constructor.

There cannot be any subclasses of the

class.

There should be more subclasses of the

class than just

Triangle.

Nothing is wrong with the code.
