Test-Driven Development (TDD) using Java Test-Driven Development (TDD) is a software development methodology where tests are written before writing the actual code. This practice ensures that the code is thoroughly tested and designed to meet the requirements from the outset. TDD consists of three main steps: write a failing test, write the minimum code to
Deep Dive into Mocking with Mockito Mocking is a crucial part of unit testing that involves creating mock objects to simulate the behavior of real objects. This helps in isolating the code under test and verifying interactions with dependencies. Mockito is a popular Java mocking framework that simplifies the creation and verification of mock objects.
Unit Testing with JUnit and TestNG Testing is a crucial part of software development, ensuring that code works as expected and remains robust over time. In Java, JUnit and TestNG are two popular frameworks for unit testing. This section will cover the basics and advanced features of both frameworks. Unit Testing with JUnit JUnit is
Deep Dive into Java Security Security is a critical aspect of software development, and Java provides a comprehensive set of APIs and tools to implement robust security mechanisms. This section covers the Java Security API, encryption and decryption using JCE (Java Cryptography Extension) and Bouncy Castle, and secure coding practices. 1. Java Security API The
Deep Dive into JavaServer Faces (JSF) JavaServer Faces (JSF) is a Java specification for building component-based user interfaces for web applications. It simplifies the development of web applications by providing a component-based framework that includes a powerful event-driven programming model and reusable UI components. Key Concepts in JSF Setting Up JSF Creating a Simple JSF
Deep Dive into Java WebSockets WebSockets provide a full-duplex communication channel over a single TCP connection, allowing for real-time data exchange between clients and servers. This is particularly useful for applications that require low latency, such as live chat applications, gaming, live notifications, and real-time data analytics. Key Concepts in WebSockets Setting Up WebSockets in
Deep Dive into RESTful Web Services using Java RESTful web services are designed to be stateless, client-server based, and able to handle CRUD (Create, Read, Update, Delete) operations using standard HTTP methods. In Java, we can build RESTful web services using JAX-RS (Java API for RESTful Web Services) and Spring REST. This deep dive will
Deep Dive into JVM Internals Understanding JVM internals is essential for optimizing Java application performance and troubleshooting complex issues. This section covers the JVM architecture and the class loading mechanism. JVM Architecture The Java Virtual Machine (JVM) is an abstract computing machine that enables Java bytecode to be executed on any platform. The JVM provides
Web Development with Java: Servlets and JSP Java Servlets and JavaServer Pages (JSP) are technologies used to create dynamic web applications. Servlets are Java programs that run on a server, while JSPs are HTML pages with embedded Java code. Together, they form the backbone of many Java-based web applications. 1. Java Servlets A servlet is
