import java.util.*;

public class ArrList {
static Scanner sc = new Scanner(System.in);
    public static void display() {
        System.out.print("Enter size of array : ");
        int size = sc.nextInt();
        
        ArrayList<String> appliances = new ArrayList<String>(size);
        for(int x = 0; x < size; x++) {
            System.out.print("Add some appliance/s : ");
            appliances.add(sc.next());
        }
        System.out.println();
        System.out.println("Display Current Array\n");
        for(int y = 0; y<size; y++) {
            System.out.println(y + ". " + appliances.get(y));
        }
        System.out.println("Current Array Size : " + appliances.size());
        System.out.print("\nEnter the scdex of appliances you want to remove : ");
        int id = sc.nextInt();
        appliances.remove(id);
        System.out.println("\nDisplay Updated Array");
        for(int z = 0; z < appliances.size(); z++) {
            System.out.println(z + ". " + appliances.get(z));
        }
        System.out.println("Updated Array Size : " + appliances.size());
    }
    
    public static void main(String[] args) {
        display();
    }
}

this is my source code

yeah next() reads until the next whitespace, not the entire input/line

use nextLine, and also

If Scanner#nextLine reads an empty line after calling a different Scanner#next method, take a look at this StackOverflow post.
