finish the code: Given string userString$1$ on one line and string userString$2$ on a second line, assign lengthDiff with the length of the shorter string subtracted from the length of the longer string.

Ex: If the input is:

eagle

orange

then the output is:

$1$ import java.util.Scanner;

public class StringLength $\{$

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

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

String userString$1$;

String userString$2$;

int lengthDiff;

userString$1=$ scnr$.$nextLine$()$;

userString$2=$ scnr$.$nextLine$()$;
