Consider the following class:

Identify the constructors, mutator methods, and accessor

methods.

public class A

$\{$

public $A()\frac{n}{\frac{?}{?}}=2$;

public A$($int a$)\frac{n}{\frac{?}{?}}=a$;

public void $f()\frac{n++\text{;}}{\frac{?}{?}}.$

public void $g()\{f()$;$,n=2**n\%3$;$,f()$;$\}$

$//$

public int return $n+7$;

public void k$()\{$ System.out.println$($n $-14)$; $\}//$

private int $n$; $//$ What kind of variable is $n?$
