What is use of implicit objects in JSP?

JSP implicit objects are created by container while translating JSP page to Servlet source to help developers. We can use these objects directly in scriptlets that goes in service method, however we can’t use them in JSP Declaration because that code will go at class level.

We have 9 implicit objects that we can directly use in JSP page.

1. out Object

3. response Object
4. config Object
5. application Object
6. session Object
7. pageContext Object
