<%– JSP Comment –%>

<!– HTML Comment –>

In JavaServer Pages (JSP), there are two types of comments:

  1. HTML Comments:
    • Syntax: <!-- This is an HTML comment -->
    • Description: HTML comments in JSP are similar to standard HTML comments and are used for adding comments to the generated HTML output. These comments are visible in the HTML source code of the final page when viewed in a web browser.
  2. Java Comments:
    • Syntax: <%-- This is a JSP comment --%>
    • Description: Java comments in JSP are used for adding comments that are not visible in the generated HTML output. These comments are typically used for commenting out blocks of Java code within the JSP page. The content within <%-- and --%> is treated as a comment and is not processed during the execution of the JSP.

In summary, the key difference between HTML comments and Java comments in JSP lies in their visibility in the final HTML output. HTML comments are visible in the generated HTML, while Java comments are not and are primarily used for commenting out Java code within the JSP page.
