I am working on this lab and no matter what I do I can't get this coding to work correctly. Please help!!

Here's the assignment.

$1\mathrm{.}38$ Variables, input, and casting $($Java$)$

$(1)$ Prompt the user to input an integer, a double, a character, and a string, storing each into separate variables. Then, output those four values on a single line separated by a space. $($Submit for $2$ points$).$

Enter integer: $99$

Enter double: $3\mathrm{.}77$

Enter character: z

Enter string: Howdy

$993\mathrm{.}77$ z Howdy

$(2)$ Extend to also output in reverse. $($Submit for $1$ point, so $3$ points total$).$

Enter integer: $99$

Enter double: $3\mathrm{.}77$

Enter character: z

Enter string: Howdy

$993\mathrm{.}77$ z Howdy

Howdy z $3\mathrm{.}7799$

$(3)$ Extend to cast the double to an integer, and output that integer. $($Submit for $2$ points, so $5$ points total$).$

Enter integer: $99$

Enter double: $3\mathrm{.}77$

Enter character: z

Enter string: Howdy

$993\mathrm{.}77$ z Howdy

Howdy z $3\mathrm{.}7799$

$3\mathrm{.}77$ cast to an integer is $3$

Here's my coding:

import java.util.Scanner;

public class BasicInput $\{$

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

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

int userInt $=0$;

double userDouble $=0\mathrm{.}0$;

char userChar;

String userString;

System.out.print$("$Enter integer: $")$;

userInt $=$ scnr$.$nextInt$()$;

System.out.print$("$Enter double: $")$;

userDouble $=$ scnr$.$nextDouble$()$;

System.out.print$("$Enter character: $")$;

userChar $=$ scnr$.$next$().$charAt$(0)$;

System.out.print$("$Enter string: $")$;

userString $=$ scnr$.$next$()$;

System.out.println$($userInt $+""+$ userDouble $+""+$ userChar $+""+$ userString$)$;

System.out.println$($userString $+""+$ userChar $+""+$ userDouble $+""+$ userInt$)$;

System.out.println$($userDouble $+"$ cast to an integer is $"+($int$)$userDouble$)$;

return;

$\}$

$\}$

Here's the output I$\text{'}$m getting which is incorrect:

Program output displayed here

Enter integer: Enter double: Enter character: Enter string: $993\mathrm{.}77$ z Howdy

Howdy z $3\mathrm{.}7799$

$3\mathrm{.}77$ cast to an integer is $3$
