9. 47. 32. Checking for Position from End


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"));

  }

}
