public int lastIndexOf(Object element)
public int lastIndexOf(Object element, int index)

These methods use equals() to check for equality.

Return -1 if not found.

The lastIndexOf() reports the position from the beginning, but starts at the end.

import java.util.Vector;

public class MainClass {
  static String members[] = { "A", "I", "C", "D", "E", "F", "G", "H", "I", "J" };

  public static void main(String args[]) {
    Vector v = new Vector();
    for (int i = 0, n = members.length; i < n; i++) {
      v.add(members[i]);
    }
    System.out.println(v);
    System.out.println(v.lastIndexOf("I"));
  }
}

[A, I, C, D, E, F, G, H, I, J]
