Request Parameters in Servlets with example using Tomcat 10
In this video, you will learn what Request Parameters are in Java Servlets and how data flows from the HTML form (client) to the Servlet (server).
We walk through a simple example where the user enters Name and Age, submit these details through an HTML form, and the servlet reads and displays them using:
request.getParameter("parameterName");
