Java Array List Example Program

package com.practice.list;
import java.util.*;
public class ArrayListExample {

   public static void main(String args[]) {
      // create an array list
      ArrayList al = new ArrayList();
      System.out.println("Initial size of al: " + al.size());

      // add elements to the array list
      al.add("M");
      al.add("A");
      al.add("D");
      al.add("D");
      al.add("Y");
     
      al.add(1, "A");
      System.out.println("Size of al after additions: " + al.size());

      // display the array list
      System.out.println("Contents of al: " + al);

      // Remove elements from the array list
      al.remove("D");
      al.remove(2);
      System.out.println("Size of al after deletions: " + al.size());
      System.out.println("Contents of al: " + al);
   }
}

Output :

Initial size of al: 0
Size of al after additions: 6
Contents of al: [M, A, A, D, D, Y]
Size of al after deletions: 4
Contents of al: [M, A, D, Y]
