Can a session store primitives as of scwcd5?

[Adam Mazurek]

Hello

When I see question like the one in the topic I think the right answer should be "yes". Am I right?

Hi,

Can a session store primitives as of scwcd5?

No should be the answer. You can only store Object in setAttribute() method. It must be a Object (which extends java.lang.Object)

[Bryan Basham]

If you are using Java5, then the answer is 'yes' because Java will automatically converted your primitive value into a wrapper object before storing it into the session attribute map. This Java5 feature is called autoboxing. So this code works fine:

int x = 47;
request.setAttribute("x", x);
....
x = (Integer) request.getAttribute("x");  // I think the cast is necessary, but maybe not... try it!

HTH,
Bryan

Or the answer is No as the autoboxing is only a pleasant syntactic sugar on top of the features supported by earlier versions of Java.

Or the answer was always yes as the Wrapper classes can store primitive values.

So if you get a question that says can you store primitives in a session the question is ambiguous and the answer might be the Japanese "mu"
