firstElement()


The firstElement() method is used to return the first component (the item at index 0) of this vector.

Syntax:
public E firstElement()


Example:

import java.util.Vector;

public class VectorDemo {
   public static void main(String[] args) {
      // create an empty Vector vec with an initial capacity of 4      
      Vector vec = new Vector(4);

      // use add() method to add elements in the vector
      vec.add(4);
      vec.add(3);
      vec.add(2);
      vec.add(1);

      // let us check the first element of the vector
      System.out.println("First element is :"+vec.firstElement());                  
   }
}
