Whats Wrong with my program.

import java.util.Scanner; $//$ Import the scanner class

Public class Multiples$\{$

$//$ assumes that n is a postive integer

public static boolean isMultipleof$($int n$1,$int n$2)$

$\{$

if$(($n$1\%$n$2)==0)$

return true;

else

return false;

$\}$

$//$ Driver Code

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

$\{$

Scanner input$=$new Scanner$($System$.$in$)$;

int n$1=0$;

int n$2=0$;

$//$accept inputs from user

System.out.println$("$Enter first"$)$;

n$1=$input.nextInt$()$;

System.out.println$("$Enter second number"$)$;

n$2=$input.nextInt$()$;

if $($isMultipleof$($n$1,$n$2)==$ true$)$

System.out.printf$($n$1+"$is a multiple of $"+$n$2)$;

else

System.out.printf$($n$1+"$ is not a multiple of $"+$n$2)$;

input.close$()$;

$\}$
