Consider the following declarations:

public interiace Measurer

$1$

int measure$($Object anobject$)$;

$\}$

public class StringlengthMeasurer implements Measurer

I

public int measure$(q,$

$\{$

String str $=($String$)$ anobject;

return str$.$ length$()$;

$\}$

$\}$

What parameter declaration can be used to complete the callback measure method?

String aString

Object aString

Object anObject

String anobject
