Identify areas where the following code could be refactored. Explain how you would refactor each area that you chose.

public class ExampleCode $\{$

public static void main$($String$[]$ args$)\{$

int thenum $=10$;

int x $=5$;

int ans $=$ add$($x$,$ thenum$)$;

System.out.println$("$The sum of $"+$ x $+"$ and $"+$ thenumb $+"$ is: $"+$ ans$)$;

int ans$2=$ subtract$($x$,$ thenum$)$;

System.out.println$("$The difference between $"+$ x $+"$ and $"+$ thenum $+"$ is: $"+$ ans$2)$;

$\}$

public static int add$($int x$,$ int y$)\{$

return x $+$ y;

public static int add$2($int x$,$ int y$,$ int z$)\{$

return x $+$ y $+$ z;

$\}$

public static int subtract$($int x$,$ int y$)\{$

return x $-$ y;
