If the scriptlet produces output, the output is stored in the out object, from which you can display it.

Which one is faster servlet OR jsp?
Servlet is more faster than JSP, but JSP is more convenient than Servlet and JSP is clearly superior, shorter, simple and easier to use. JSP can be perceived as Java in HTML code. JSP require no explicit compilation as like servlets and can keep in the web application server as HTML file. The web application server in turn compile the java code in JSP and load it in its library for future execution. Servlet can be perceived as HTML in Java code. The servlet is the class file, which would be loaded in the web application server as a program. The program output will be directed to the outstream object which in turn direct to the client as HTML elements.

What is the difference between script and scriptlet?
"script" is an HTML tag used to include JavaScript on a web page. Example: <HTML> <body> <script type="text/javascript"> document.write("hi there"); // javascript interpreted by the browser </script> </body> </HTML> "Scriptlet" is a JSP construct used to include Java in a JSP page. Example: <HTML> <body> <% // this is a scriptlet response.getWriter().write("hi there"); // Java executed on the server %> </body> </HTML> Here the result (an HTML document with the text "hi there") is the same in both cases, but the mechanisms are different - Javascript runs in the browser (any browser), while the JSP scriptlet is executed on the server and needs a server with JSP support.
