Que: What is the difference between both implicit objects i.e. 'page' and 'pageContext'?
===================================================================
Answer :

-Implicit object 'page' holds the reference of the current JSP equivalent servlet object, whereas the implicit object 'pageContext' holds multiple details about the current JSP program like this, request, response objects, buffer size, autoflush mode, error page etc....

Implicit object 'page' is useful for differentiating scriptlet tag % % variable from declaration tag %! % variable names when both have the same names.

-Using pageContext object we can do multiple operations like getting/receiving other implicit objects and creating various scopes of attributes....

In JSP Equivalent Servelt code is

final jakarta.servlet.jsp.PageContext pageContext;

final java.lang.Object page = this;

pageContext = _jspxFactory.getPageContext(this, request, response,
null, true, 19456, true);
null, : Error Page
true: Session object
buffer size: 19456,
autoFlush: true
