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

How to develop REST CRUD API using Spring Boot ?
It will not be an overstatement if I say that we can't develop an enterprise application without using webservices as an integration layer. Generally, we develop webservices in the form of either a producer or a consumer or both. However Producer is very important for us because we develop it in Java only. Also, we have full control of database interaction logic implementation with us. Now you might have interpreted the significance of our article 'How to develop REST CRUD API using Spring Boot?'. On the other hand, Consumer can be Angular Application, ReactJS Application, Android Device, iOS Device and many others or even our favorite java based RestTemplate(Spring Boot REST Client). Our focus in this article is on developing producer
How to Extract Text from an Image Using Java?
Many a times we come across a requirement when we need to extract text from an image. This process is also known as Optical Character Recognition (OCR). OCR is extensively useful in various use cases, such as converting physical documents into digital formats to make them searchable and editable, automating data entry processes to minimize errors, extracting information from checks in banking institutions, digitizing patient records in the healthcare industry, converting case files into digital formats in the legal department, digitizing textbooks, extracting information from invoices, receipts, and many more. This article will focus on How to Extract Text from an Image Using Java?. Although there are many online image-to-text converter tools are introduced that can extract text from an image
Spring Cloud Annotations With Examples
Introduction of new Annotations reduces the development efforts day by day. Needless to say, as a developer, we can't think of the development of an enterprise level application without using annotations, especially in applications that use Spring or related frameworks. Furthermore, we come across the Spring Cloud framework when we develop a Microservices based application. Now-a-days, there is a high demand of Microservices based applications in the industry. Therefore, it becomes very crucial to know the annotations used in Spring Cloud. Hence, in this article, we are going to discuss 'Spring Cloud Annotations With Examples'. We can't deny from the fact that the cloud is the future and, in the upcoming days, we will be seeing a lot of Java based
How to reduce boilerplate code in REST API Spring Data REST
In previous article on REST API Development, we have already seen that how we can develop a REST API with minimum lines of code. Still, we have more scope to reduce lines of code using a concept called 'Spring Data REST' in Spring Boot. So, our title of the article is 'How to reduce boilerplate code in REST API Spring Data REST'. In Spring Data REST concept we don't have to write even RestController and its methods. The Spring Data REST dependency will take care of it using HATEOAS (Hypertext as the Engine of Application State). HATEOAS project is a library of APIs that we can use to easily create REST representations. Spring Data REST provides hyperlinks to access REST operations
An Overview On JavaScript Technologies
AN OVERVIEW ON JAVASCRIPT TECHNOLOGIES || COMPLETE GUIDE There are many programming languages that are being used for developing websites, games and apps. Some are specific to use for special purposes like HTML, CSS and JavaScript are used for website or web app development. PHP is frequently used to build dynamic web pages and web applications. It can generate HTML, process forms, and interact with databases, making it a popular choice for building websites. Node.js is suitable for building real-time web applications, such as chat applications, online gaming platforms, and collaborative tools. Python is extensively used for data science and data analytics. Python's extensive libraries, including TensorFlow, PyTorch, and scikit-learn, make it a favorite choice for developing machine learning models and

WebClient in Spring Boot
A typical modern web application generally has four well known layers i.e. Presentation Layer, Service Layer and Data Layer, and an Integration Layer. The Integration layer generally works with the web services concept and connects two different applications to exchange data between them. One application refers to producer/provider, whereas other refers to consumers. Here, we will discuss about REST consumer/client API using WebClient in Spring Boot. The traditional way of implementing REST client API is by using RestTemplate. However, we have already gone through the RestTemplate in another article where we had developed different operations to consume REST API. Now, we must have a question in mind ‘How to write REST Consumer API using WebClient in Spring Boot?’. Needless to say, WebClient
