Introduction Software development is entering a new phase in which artificial intelligence is moving beyond code suggestions toward systems capable of completing entire software engineering tasks. Earlier AI programming assistants focused primarily on generating functions, explaining syntax, and completing code snippets. Modern autonomous coding agents can inspect repositories, identify [...]

This example explains Servlet and JDBC Connectivity with a MySQL database. As can be seen in the output, this example shows a list of users which it fetches from a database table. Further, we use MySQL Workbench 8.0 CE for creating our database. Creating Database Table To begin with, we create a database called d1. Further, we use the <use d1> command and to make the […]
The following Deep Learning Practice Exercise comprises important deep learning concepts. As a matter of fact, implementing a deep learning algorithm becomes easy with the help of certain python packages. Furthermore. TensorFlow and Keras are two such libraries that you can use in deep learning. While TensorFlow is an open-source library that offers both high-level and low-level APIs, Keras has […]
The following Python Practice Exercise comprises basic programming constructs, control flow, and functions in python. Also, the learner can apply the concepts of data structures like lists, tuples, sets, and dictionaries in python applications. Apart from this, it includes the use of object-oriented programming features of python to develop applications. Additionally, the following Python Practice Exercise aims to make you learn how […]
In this article, I will explain When and How to Use Servlet Annotations. In fact, the Servlet version 3.0 introduces the concept of annotations. As a result, it is no longer required to use only the web.xml file for configuring the servlets. Hence, we have now annotations to configure various components of the servlet. Accordingly, IDEs like Eclipse have the support of […]
In this article, I will explain how to perform Set Operations in LINQ. Basically, Language Integrated Query (LINQ) has several query methods for performing set operations such as union, intersection, and set difference. Query Methods for Performing Set Operations in LINQ The following section provides a description of query methods available in LINQ. In fact, we can represent a set […]
In this article, I will explain how to use Quantifiers in LINQ. Basically quantifiers are operators that return a boolean value. Further, these quantifier operators return a value that indicates whether all elements in a set satisfy a particular condition or only few. Also, whether a specific element is available in the set. Accordingly, the LINQ in C# provides following […]
This article explains Creating Deployment Descriptor in a Dynamic Web Project in Eclipse JEE. Basically, a deployment descriptor is called web.xml and contains configuration information regarding a dynamic web application. However, when we create a dynamic web project in Eclipse IDE, the web.xml file is not available by default. Therefore, we need to create this file explicitly. Steps for Creating […]
This article explains Registering a Servlet in Deployment Descriptor. Basically, registering a servlet in the deployment descriptor requires providing the <servlet> tag in the web.xml file. Also, within this tag, the <servlet-name>, and <servlet-class> tags specify the name of servlet and associated java class respectively. Additionally, we can also specify <init-parameter> tags to provide the initialization parameters for a servlet. […]
Basically, a deployment descriptor refers to a configuration file in a web application. Whenever we create a J2EE application, it includes web components comprising of servlets and JSP files, For the purpose of managing the dynamic web application, we can create a web.xml file. In fact, the web.xml is our deployment descriptor. This web.xml file contains information regarding URL mapping, registering servlets, […]
In this article, I will explain Servlet and its Life Cycle. To begin with, let us first understand what a servlet is. What is a Java Servlet? In fact, the java servlet is a technology to create dynamic web pages. In short, servlets are classes that reside on a web server or application server. Furthermore, a webserver executes a servlet whenever […]
