Printing all the Elements in a Vector

A Vector is a linear list of elements, just like an array. As with an array a counting loop can be used to visit each element in order. (Note: an alternate method, using an Enumeration will be discussed later.) The following is an example:

import java.util.* ;

class VectorEg
{

  public static void main ( String[] args)
  {
    Vector names = new Vector( 10 );

    names.addElement( "Amy" );
    names.addElement( "Bob" );
    names.addElement( "Chris" );
    names.addElement( "Dan" );
    names.addElement( "Elaine" );
    names.addElement( "Fred" );

    for ( int j=0; j < names.__________(); j++ )
      System.out.println( j + ": " + names.__________(j) ); 

  }
}
