The comment explains what the following loop does. Use a method instead.

$//$ Counts the number of spaces

int spaces $=0$;

for $($int i $=0$; i $<$ input.length$()$; i$++)$

$\{$

if $($input$.$charAt$($i$)==\text{'}\text{'})\{$ spaces$++$; $\}$

$\}$

import java.util.Scanner;

public class HelperMethods

$\{$

$/**$

Gets the number of spaces in a string.

@param str any string

@return the number of spaces in str

$*/$

$/*$ Your code goes here $*/$

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

$\{$

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

String line $=$ in$.$nextLine$()$;

System.out.println$($countSpaces$($line$))$;

$\}$
