What is wrong with the following code, which attempts to return the number of factors of a given integer n$?$ Describe how to fix the code.

public int countFactors$($int n$)$

$\{$

$$for $($int i $=1$; i $<=$ n; i$++)$

$\{$

$$if $($n $\%$ i $==0)//$ check if i is a factor of n

$\{$

$$return i;

$\}$

$\}$

$$return $0$;

$\}$
