session objects

[morc]

hi,

i was wondering how to put an array of ints into an Object.

session.setAttribute(String,Object);

how can i make it so that i can retrieve whats in the attribute into an
array of ints.

meaning something along the lines of

int[] = session.getAttribute(String);

i know that code won't work. if anyone knows what i mean and can help
me, please post.
thanks alot

Use an ArrayList of the Object 'Integer'.

Integer i1 = new Integer(1);
Integer i3 = new Integer(3);

ArrayList list = new ArrayList();
list.add(i1);
list.add(i3);

session.setAttribute(String, list);

....then...

ArrayList listFromSession = (ArrayList)session.getAttribute(String);

Then listFromSession is the ArrayList of Integer objects.


Actually, I think arrays are Java Objects, so just put your int[] array
into the Session using setAttribute() and when you do getAttribute just
cast to an int array. I'm pretty sure that will work.

Each array is also an object. So try the following code :

session.setAttribute("intArray", ia);

ia = (int[]) session.getAttribute("intArray");
