Why is Spring framework so popular ? java Spring Spring Boot by devs5003 - May 21, 2024April 7, 20260 We have various frameworks in Java. Spring framework is most popular out of them. Some other commonly used frameworks are Struts, JSF, but Spring has already dominated all of them. Let's understand why is Spring framework so popular ?. At its core, the Spring Framework includes the principles of simplicity, modularity, and loose coupling. It provides developers with a unified programming model that simplifies the complexities of enterprise application development. With its popular dependency injection mechanism, Spring allows the creation of highly modular and testable code. It also makes developers free from the burden of managing complex dependencies manually. Before directly coming to 'Why is Spring Framework so Popular ?', let's first understand the basic terminology 'What is a Framework?'. What is

Continuation-Passing Style-CPS in Java Core Java java Programming by devs5003 - May 15, 2024May 17, 20240 Continuation-Passing Style (CPS) is a programming model used to manage control flow in software applications. It provides a way to handle asynchronous or callback-based programming by explicitly passing control from one function to another. Although this concept was originally generalized in functional programming languages like Scheme, Haskell, and Scala, but CPS can also be implemented in object-oriented languages like Java. In this article, we'll analyze the concepts behind Continuation-Passing Style-CPS in Java and explore its implementation with code examples. What is Continuation-Passing Style? In traditional programming model, control flow is managed through the call stack. When a function is called, the current execution context is pushed onto the stack, and when the function returns, the context is popped off the stack, allowing
Core Java Interview Questions with Detailed Answers Interview Core Java java by devs5003 - May 15, 2024November 4, 20250 Here in this section we will see Core Java Interview Questions and answers which will be valuable for any type of interview in Java Programming Language. I am sure that you will find some unique questions that you may rarely see in other sources. Moreover, you will find clear explanations of the answers to each question. When you go through the answers you will find that while answering the questions related new terms are also explained. If you need any other question to be added here, don't hesitate to put your notes in the comment section. Why are the Java primitive data types not objects? Why is Java not a pure Object-Oriented programming Language? Objects always consume more memory than primitives. If
How to Implement Feign Client in Spring Boot Microservices? Feign Client java Microservices Spring Boot Spring Cloud by devs5003 - May 10, 2024November 11, 20259 When two web applications communicate with each other for data exchange, they work on Producer-Consumer technique. An application who produces data is known as a Producer/Provider application. Similarly the one who consumes data is known as Consumer application. As a Java developer, we might be very familiar with REST API for Producer application whereas RestTemplate for Consumer application. With Microservices based application also, two Microservices communicate with each other and follow the Producer-Consumer model. Here, in consumer side, we use a concept 'Feign Client' as a better option instead of RestTemplate in order to minimize our effort of coding. Therefore, our topic of discussion is 'How to Implement Feign Client in Spring Boot Microservices?'. Apart from consuming REST services in an

Record vs. Lombok Core Java java Lombok Record In Java by devs5003 - May 1, 2024January 24, 20250 Every Java developer attempts to reduce the boilerplate code whenever it is possible. Undoubtedly, the new JDK versions and even modern frameworks like Spring, Spring Boot have already contributed much to make it possible. In this matter, Records in Java 16 and Lombok library are also known to reduce boilerplate code. Java 16 Records are a native language feature introduced in Java 16. Lombok is a third-party library that provides annotations to eliminate repetitive common tasks. In this detailed comparison 'Record vs. Lombok', we will explore the definition, syntax, usage, advantages, disadvantages, and practical examples of Java 16 Records and Lombok, and compare them based on various parameters. Let's start with what is Record and what is Lombok. Record vs. Lombok: Purpose, Usage,
Java Scheduler: How to Schedule a Job in Java Spring Boot Scheduler Scheduling java Spring Spring Boot by devs5003 - April 26, 2024May 6, 202545 Sometimes we come across a situation when we expect a task should execute only at a particular point of time or re-execute within a particular time interval. Simultaneously, our client expects a functionality to be executed at a particular time on an hourly basis, daily basis, weekly basis, monthly basis or even some other as well. In fact, in all these types of situations we implement scheduling to get the requirements fulfilled accordingly. For example, one of the most popular implementation is the report generation at a particular time. On the other hand, almost every client expects this functionality to have in the project. Currently the most popular one is the PDF report. Consequently, our topic 'Java Scheduler: How to Schedule
Java Testing Frameworks Core Java java Java Testing by devs5003 - April 22, 2024November 26, 20240 A Comprehensive Guide to Java Testing Frameworks Testing in Java applications is an essential part of the software development process It plays a vital role in reliability, code quality, and the complete success of the application. There are various testing frameworks that make testing easier for developers & testers. These frameworks provide systematic conditions that allow developers to write, organize, and execute tests in a structured manner. Their primary purpose is to validate the correctness, functionality, and performance of the code under diverse conditions. A Comprehensive Guide to Java Testing Frameworks These frameworks facilitate different types of testing methodologies. For example, Unit testing focuses on verifying the smallest parts of an application, such as individual methods or classes. On the other hand, Integration testing
Spring Dependency Injection java Spring Spring Boot Spring Core by devs5003 - April 18, 2024November 6, 20250 If you are working in a project where spring is being used, you must have heard about the term 'Spring Dependency Injection'. If not, this is the right time to dig into it as much as possible without further delay. Needless to say, Spring dependency Injection is the heart of the whole Spring Framework. I would also suggest you to go through the practical knowledge of it. However, it is also true that someone can't understand the concept of Spring Dependency Injection only having the theoretical knowledge. If you are expecting to learn all the basic and crucial concept behind the Spring Dependency Injection step by step, and if you don't want to revise the concept more than a hundred times
