Consider the following code:

class SuperSingleton implements Cloneable $\{$

QOverride

protected Object clone$()$

throws CloneNotSupportedException

$\{$

return super.clone$()$;

$\}$

bs

$//$ Singleton class

class Singleton extends SuperSingleton $\{$

$//$ public instance initialized when loading the class

public static Singleton instance $=$ new Singleton$()$;

private Singleton$()$

$\{$

$//$ private constructor

hs

$\}$

public class Client $\{$

public static void main$($Stringl$]$ args$)$

throws CloneNotSupportedException

$\{$

Singleton si $=$ Singleton. instance;

Singleton s$2=($Singleton$)$si$.$clone$()$;

System. out.println$("$sl hashCode:$-"$

$+$ s$1.$hashCode$())$;

System. out.println$("$s$2$ hashCode:$-"$

$+52.$hashCode$())$;

$\}$

$\}$
