import java.util.ArrayList;

public class MainClass {
public static void main(String args[]) {
ArrayList al = new ArrayList();

System.out.println("Initial size of al: " + al.size());

//Elements of array
al.add("C");
al.add("A");
al.add("E");
al.add("B");
al.add("D");
al.add("F");
al.add(1, "A2");

System.out.println("Size of al after additions: " + al.size());

System.out.println("Contents of al: " + al);

al.remove("F");
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: 7
Contents of al: [C, A2, A, E, B, D, F]
Size of al after deletions: 5
Contents of al: [C, A2, E, B, D]
