Thank You Regards Rahul Singh -----Original Message----- From: javaprogrammingwithpassion@googlegroups.com [mailto:javaprogrammingwithpass...@googlegroups.com] On Behalf Of Lawrence Louie Sent: Friday, October 15, 2010 4:42 AM To: Java Programming Online Training Course By Sang Shin Subject: [java programming] question on autoboxing. Hi, When using autoboxing, how can I find out what the data type is inside the elements: Vector<object> v = new Vector<Object>(); v.add( "Hello World" ); v.add( 10 ); v.add( 11.0 ); For example, if I need to iterator each element in the vector here, how can I find out the type of the object here. I cannot do the instanceOf, since the element here do not share the interface. Thx.
