Being a Java developer, one might have encountered some design patterns that help us in structuring our code and make it more reusable and maintainable. Two of these design patterns are the State pattern and the Strategy pattern. The use case of these design patterns is almost the same. However, they are different from each other in many ways. In this article, we are going to explore the differences between state and strategy design patterns in Java. State vs Strategy Design Pattern State Design Pattern The State pattern is a behavioral design pattern that allows an object ... Read More

Both RMI and DCOM are the technologies that serve to enable distributed object computing. The RMI is a Java-based technology, DCOM, on the other hand, is developed by Microsoft. Although they are built for the same purpose by two technical market giants, there exist some significant differences in terms of design, implementation and usage. We are going to compare and list some differences between RMI and DCOM in this article. RMI vs DCOM Distributed Objects To understand the differences between RMI and DCOM, it is necessary to understand distributed object computing as both terms come under the same umbrella. ...

Introduction Networking is a critical component of modern software development. In Java, one of the ways we can establish network communication is by using sockets. While most are familiar with stream-oriented, connection-based TCP sockets, this article focuses on the connectionless, packet-oriented UDP DatagramSockets and how to work with them effectively. Understanding UDP and DatagramSockets User Datagram Protocol (UDP) is one of the core protocols in the Internet Protocol Suite. Unlike TCP, it is connectionless and does not guarantee delivery, order, or error-checking of data packets. However, it is faster and more efficient for lightweight or time-sensitive applications In Java, the ... Read More

Introduction Parallel processing is a cornerstone of modern computing, allowing us to take full advantage of multi-core systems. In the realm of Java, one of the tools at our disposal to utilize this power is parallel streams. This article delves into the concept of parallel streams in Java, exploring their functionality, benefits, and how to use them effectively. Understanding Java Parallel Streams Java Streams were introduced in Java 8 as a way to perform complex data processing tasks on collections of objects, often referred to as a stream of data. These operations can be executed sequentially or in parallel. A ... Read More

Introduction The Abstract Window Toolkit (AWT) forms the backbone of Java's original platform-independent windowing, graphics, and user-interface toolkit. One of its key components, the Graphics class, plays a vital role in creating and controlling graphical content in Java applications. This article provides an in-depth overview of the Graphics class in Java AWT, including its functionality, key methods, and example usage Understanding the Graphics Class The Graphics class, located within the java.awt package, is an abstract superclass that provides a unified interface for drawing shapes, text, and images onto the screen. It encapsulates the basic drawing operations that every device must ... Read More

Introduction In Java, the Adapter design pattern plays a crucial role in helping disparate classes work together by converting the interface of one class into an interface expected by the clients. But Java swings the Adapter pattern into a different dimension with the introduction of Adapter Classes. This article delves into Java Adapter Classes, understanding their purpose, their benefits, and how to use them effectively. Adapter Classes in Java In Java's event handling mechanism, adapter classes are abstract classes provided by the Java AWT (Abstract Window Toolkit) package for receiving various events. These classes contain empty implementations of the methods ... Read More

Introduction Heap pollution is a situation that arises in Java during runtime when a variable of a parameterized type refers to an object that is not of that parameterized type. It's a term often encountered when working with generics. This article seeks to unravel the concept of heap pollution in Java and provide guidance on how to resolve and prevent it What are Generics in Java? Before we delve into heap pollution, let's quickly review Java generics. Generics were introduced in Java 5 to provide type-safety and to ensure that classes, interfaces, and methods could be used with different data ... Read More

Introduction In Java, concurrency and multithreading are fundamental concepts that facilitate simultaneous execution of two or more parts of a program to maximize the utilization of CPU. The start() method plays a pivotal role in this process. This article delves into the workings of the start() function in Java multithreading, explaining its purpose and significance. Java Multithreading A Brief Overview Multithreading is one of Java's core features, allowing multiple sequences of code, known as threads, to execute concurrently within a single program. By enabling concurrent execution, Java allows more efficient use of CPU resources, particularly on systems with multiple ... Read More

Introduction Java continually evolves to meet modern programming needs, and one of its newest features, Java Records, introduced in JDK 16, simplifies the task of modeling data. This article sheds light on Java Records, detailing how they work alongside constructors and methods to streamline your Java coding experience Understanding Java Records Java Records are a type of class that aims to simplify the representation of "plain data" in your applications. Essentially, they are immutable data carriers used to encapsulate a few final fields, termed 'components', along with methods to access them Before Records, developers had to write a substantial amount ...

Introduction Servlets have long been a cornerstone of Java-based web development. However, as web technologies have evolved, several alternatives to Servlets have emerged, offering various features and paradigms that suit different development needs. This article provides an overview of these alternatives and discusses their strengths and applicability in different contexts Understanding Servlets Servlets are Java programs that run on a web server, acting as a middle layer between a request from a web browser or other client and the server's response. Despite being a powerful technology for building web applications, Servlets can become complex when used in large-scale applications. Let's ... Read More
