  2. Hi Think Tank,
    I have some interview questions which were asked to me, please try to answer this.
    1. can u have 2 overlaod methods with same same args but diff return types
    2. List and Set, (ordered) how is set stored wat impls of set u used he asked me
    3. write a plandrome example in java code
    4. write producer consumer thread code in java
    5. difference between The JSP include directive and jsp:include
    ans: The advantage of jsp:include is that it will always check for changes in the included file
    It’s actually pretty simple: jsp:include includes the response from the included URI, rather than the URI itself. This means that the indicated URI is interpreted and the resulting response is included. If the page is HTML, you get the HTML essentially unchanged. But if it’s a Perl script, a Java servlet, or a CGI program, you’ll get the interpreted result from that program. While this usually turns out to be HTML, the actual program is just a means to an end. And, because interpretation happens at every page request, the results are never cached as they were with the include directive. It’s such a minor change, but it makes all the difference in the behavior you see.
