package beginnersbook.com;
import java.util.ArrayList;
public class RemoveExample {
   public static void main(String args[]) {
       //String ArrayList
       ArrayList<String> al = new ArrayList<String>();
       al.add("AB");
       al.add("CD");
       al.add("EF");
       al.add("GH");
       al.add("AB");
       al.add("YZ");
       System.out.println("ArrayList before remove:");
       for(String var: al){
            System.out.println(var);
       }
       //Removing 1st element
       al.remove(0);
       //Removing 3rd element from the remaining list
       al.remove(2);
       //Removing 4th element from the remaining list
       al.remove(2);
       System.out.println("ArrayList After remove:");
       for(String var2: al){
             System.out.println(var2);
