on vectors

[quipy]

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 )

 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()); 
 } 
}
