Why do I get java.lang.IllegalStateException: Scanner closed [closed]

Question

Silly question but I've been receiving this error message and i don't understand the error message. Any help in helping me understand my short comings would be much appreciated

    import java.util.Scanner;
    public class Exercise9 {
    public static void main(String[] args) {
        
    Scanner input = new Scanner(System.in);

    System.out.print("Enter x coordinate for point 1: ");   
    double x1 = input.nextDouble();
    input.close();

    System.out.print("Enter y coordinate for point : ");    
    double y1 = input.nextDouble();
    input.close();

    System.out.print("Enter x coordinate for point 2: ");   
    double x2 = input.nextDouble();
    input.close();

    System.out.print("Enter y coordinate for point 2: ");   
    double y2 = input.nextDouble();
    input.close();
        
    double distance = Math.sqrt((x2-x1)*(x2-x1)+(y2-y1)*(y2-y1));
    System.out.println("The distance between the two points is" +distance); 
     }
     }
