[1545]New and old way of creating a list

//Old Way
myList.add ( "hello" ) ;
myList.add ( "goodbye" ) ;
// myList.add ( new Date ( ) ) ; This would compile but cause failures later
Iterator it = myList.iterator ( ) ;
while ( it.hasNext ( ) ) {
String s = ( String ) it.next ( ) ;
System.out.println ( s ) ;

//J2SE 1.5 way
List < String > myList = new ArrayList < String > ( ) ;
