E remove(int index): Removes the element at the specified position in this list.
booleanremove(Object o): Removes the first occurrence of the specified element from this list, if it is present.


  import java.util.ArrayList;

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

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

        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);
    }
}

The 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]
