on vectors

first of all, thanks to all who've helped me thus far... i really appreciate it.

1. how do i determine the number of elements in a vector?
i tried:

i = vectorName.elementCount();

but it doesnt work.

2. if the vector stores user-defined objects (and these objects consist of int, string, date etc), can i access a particular attribute of an object in the vector directly? i.e.

int retrieved;

retrieved = vectorName.elementAt(0).age; //where age is of int type

1.
i = vectorName.size();

2.
Sure you can
retrieved = ((ClassOfStoredObject)vectorName.elementAt(0)).age;
should be working (haven't tried it :))

Code:

---

import java.util.Vector;
 
 class X{
  private String greeting;

  public X(String greeting){
  this.greeting = greeting;
  }
  public String getGreeting(){
  return greeting;
  } 
}

public class Z {
  public static void main(String[] args){
  Z z = new Z();
  z.invoke();
 }

  private X x;
  private Vector v = new Vector();

  private void invoke(){
  v.addElement(new X("Hello"));
  x = (X) v.elementAt(0);
  System.out.println(x.getGreeting());
 }
}
