Try something like

String[ ] convert( Vector _v ) // _v contains strings or something that can
// be cast to a string
{
String[ ] array = new String[ _v.size( ) ];

for( int idx = 0; idx < _v.size( ); idx++ )
array[ idx ] = (String)_v.elementAt( idx );

return array;
}

import java.util.* ;
 
public class Test1  {
 
	public static void main(String args[]) {
		Vector v = new Vector ( ) ;
		v.add ( "hello1" ) ;
		v.add ( "hello2" ) ;
		v.add ( "hello3" ) ;
 
		String[] s = (String[] ) v.toArray ( new String[v.size()] );
 
		int len = s.length ;
 
		for ( int i = 0 ; i < len ; i++ ) {
			System.out.println ( s[i] ) ;
		}
	}
}
