I am working on my rectanglar calculator in Java. I was comparing my code mport java.util.Scanner;

public class RectangleCalculator $\{$

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

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

System.out.println$("$Welcome to the Area and Perimeter Calculator"$)$;

boolean continueCalculations $=$ true;

while $($continueCalculations$)\{$

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

double length $=$ input.nextDouble$()$;

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

double width $=$ input.nextDouble$()$;

double area $=$ width $*$ length;

double perimeter $=2*$ width $+2*$ length;

System.out.println$("$Area: $"+$ area$)$;

System.out.println$("$Perimeter: $"+$ perimeter$)$;

System.out.print$("$Continue$?($y$/$n$)$: $")$;

String userChoice $=$ input.next$()$;

continueCalculations $=$ userChoice.equalsIgnoreCase$("$y$")$;

$\}$

$\}$

$\}$with the example given and the example is also incorrect, please help???
