Record vs. Lombok

by devs5003 - 0

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

by devs5003 - 45

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

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

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

How to work with Apache Kafka in Spring Boot?

by devs5003 - 10

Now-a-days, many modern systems require data to be processed for the targeted purpose as soon as it becomes available. For example, as a developer, if we talk about a Logging or Monitoring system, we often require the data as soon as a problem occurs. In a nutshell, there is a high requirement of faster & robust data delivery. Here, Apache Kafka can be a good option to solve our purpose. In a single line, Apache Kafka acts as a mediator to transmit data between applications that generate data and applications that consume data. Needless to say, we are going to discuss about 'How to work with Apache Kafka in Spring Boot?' here in this topic. If you want to know the

Undoubtedly, the demand of Java 17 features became crucial after the release of Spring Boot 3.0. Needless to say, the use of Java 17 has become mandatory since Spring Boot 3.0. It also means that every Java developer should be aware of the new changes introduced in Java 17. Java 17 comes with several new features and enhancements that aim to improve developer productivity and program efficiency. In this article, we will explore some of the most significant Java 17 features, with code examples to help you understand how to use them effectively. Java 17 is an LTS (Long-term support) release of the Java programming language. As it is an LTS version, it will receive prolonged support and security updates for

Profiles In Spring Boot

by devs5003 - 4

When we work on a real time project, we maintain multiple environment for the same project. This happens because we use different infrastructures for different stages of the project. There are different useful environments that we maintain before making the project go live, such as: development (DEV), test, user acceptance testing (UAT), production (PROD). These environments are not fixed at all. Some projects may have some more environments or even sometimes less also. It totally depends on the decisions made by stakeholders involved in the specific project and its requirements. Spring Framework offers us to maintain a separate profile for each environment in order to switch over the environments with a minimal effort. Hence, our topic of discussion is 'Profiles In

Entity Relationship in JPA/Hibernate/ORM

by devs5003 - 0

Needless to say, ORM (Object Relational Mapping) concept has made the developers life easier. Developers don't need to do much work in order to map two tables in the database. If we need to maintain a relationship between two tables, utilization of an annotation in our entity/class is more than sufficient. Further, we don't need to design the DB tables. However, developers need to have a better understanding of the usage of the annotations that create a relationship between two tables. Here in this article 'Entity Relationship in JPA/Hibernate/ORM', we will discuss about the different types of relations between tables that are relevant in ORM concept. Let's start discussing our topic ‘Entity Relationship in JPA/Hibernate/ORM’ and its related concepts. Some of the

Types Of NoSQL Databases and Examples

by devs5003 - 2

NoSQL databases provide flexible, scalable alternatives to relational databases by using different data models tuned for specific application needs. This guide explains the primary NoSQL types: key-value, document, wide-column, and graph. It shows real product examples for each, and provides quick usage guidance so you can choose the right store for your application. Traditionally, we use a relational database to work with an application. Of course, a relational database is a structured database and contains multiple tables to maintain meaningful relations between them. Additionally, it uses SQL like queries to operate with data stored in the tables. In contrast, suppose we have to work with a large amount of unstructured data which is not advantageous to store in the form of tables,
