Four integers are read from input and stored into the array arrayToModify. Write a static method swapArrayPos$()$ that takes an integer array parameter and swaps the second$-$to$-$last element with the last element of the array.

Ex: If the input is $40107545,$ then the output is:

Original array: $40107545$ Changed array: $40104575$

import java.util.Scanner;

public class ArrayParameterReferences $\{$

public static void printArr$($int$[]$ arr$)\{$

int i;

for $($i $=0$; i $<$ arr.length; $++$i$)\{$

System.out.print$($arr$[$i$]+"")$;

$\}$

System.out.println$()$;

$\}$

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

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

int userNum;

for $($i $=0$; i $<$ arrayToModify.length; $++$i$)\{$

arrayToModify$[$i$]=$ scnr$.$nextInt$()$;
