As mentioned above, only scriptlet will not generate HTML. If scriptlet wants to generate HTML, it can use a variable called "out. This variable does not need to be defined. In fact, it has been pre-defined for scriptlet, and other variables are defined together. These variables will be detailed in subsequent tutorials. The following example shows how scriptlet generates HTML output:
<HTML>
<BODY>
<%
// This scriptlet declares and initializes "date"
System. out. println ("Evaluating date now ");
Java. util. Date date = new java. util. Date ();
%>
Hello! The time is now
<%
// This scriptlet generates HTML output
Out. println (String. valueOf (date ));
%>
</BODY>
</HTML>
In this example, we do not use an expression, but print the generated HTML directly to the "out" variable. This "out" variable is a type of javax. servlet. jsp. JspWriter.
