In a JSP, which of these would be invalid?<br />
<br />
1. String value = request.getAttribute(&quot;valu<wbr />e&quot;); <br />
2. request.setAttribute(&quot;valu<wbr />e&quot;, value);<br />
3. String value = request.getParameter(&quot;valu<wbr />e&quot;); <br />
4. Object value = request.getAttribute(&quot;valu<wbr />e&quot;);<br />
<br />
I think it is 4 since the object type of &quot;value&quot; will probably be a type that is not of &quot;Object&quot; type...But then isn't a type like &quot;String&quot; an &quot;Object&quot; so then 4 would be valid...Ok, now i am not sure again. &nbsp;Can someone tell me which is the invalid one and why?<br />
<br />
Thanks<br />

In a JSP, which of these would be invalid?

1. String value = request.getAttribute("value"); 
2. request.setAttribute("value", value);
3. String value = request.getParameter("value"); 
4. Object value = request.getAttribute("value");

I think it is 4 since the object type of "value" will probably be a type that is not of "Object" type...But then isn't a type like "String" an "Object" so then 4 would be valid...Ok, now i am not sure again.  Can someone tell me which is the invalid one and why?

Thanks


Easy Question - Which one of these is invalid?!?

JavaServer Pages (JSP) allow the development of dynamically generated web pages. It uses the Java programming language; JSP pages are translated into servlets at runtime, with each servlet being cached and reused until the JSP is modified. JSP allows Java code to be interleaved with static web markup content, so the resulting page can be compiled and executed on the server to deliver the content.
