Explanation / Answer

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

       //user input to decide number of guests
       System.out.print("Enter how many friends: ");
       int numOfGuests = Integer.parseInt(scan.nextLine());

       //Create a string array to store the names of your guests
       String arrayOfNames[] = new String[numOfGuests];
       for (int i = 0; i < arrayOfNames.length; i++) {
           System.out.print("Enter the name of friend " + (i+1) + " : ");
       arrayOfNames[i] = scan.nextLine();
       }
      
       //Now show your friend's name one by one
       System.out.print("Guest List: [");
       for (int i = 0; i < arrayOfNames.length; i++) {
       System.out.print(arrayOfNames[i]+',');
       }
       System.out.print("] ");
      
       //selecting random guest who can not come
       Random rand = new Random();
       int x = rand.nextInt(numOfGuests);
      
       System.out.println(arrayOfNames[x]+" won'tcome");
       //Now print the updated list
       System.out.print("Guest List: [");
       for (int i = 0; i < arrayOfNames.length; i++) {
           if(i != x){
       System.out.print(arrayOfNames[i]);
       if(i < (arrayOfNames.length-1)){ //Added Code
                   System.out.print(',');
               }
           }
       }
       System.out.print("] ");
   }
}
