Vector

[Anandiscool]

Hi,
I am confused with the statement:
"A Vector can store only object"
Vector v=new Vector();
v.addElement(10);
v.addElement("Java");
this code gives output [10 Java],
In this code, How can '10' and 'Java' be an object?
Thank you.

Autoboxing.

Google that.

"Java" means java.lang.String class ref ... so it is an Object ;)

How can '10' and 'Java' be an object?

work with the wrapper classes of java. example for your datas

Integer i1 = new Integer(10);
String s1 = new String("Java");

so i1 und s1 are objects now and you can add them to collections that need objects. see the java spec for more details.

String s1= "Java"; also makes s1 a reference to an object and you can use ordinary ints for objects because of autoboxing (present from Java 1.5) as Masijade already pointed out in reply#1.
