Java Web Development (JSP/Servlets) Services

Instead of a monolith, build your first Java microservice with Dropwizard.

Hello, my fellow programmers! I’m positive you do not want to read another complex article on how to build Java microservices. We are going to take a look at Dropwizard today. It is fairly convenient as it has everything loaded in it, i.e., Jetty, Jersey, Jackson, etc., and also provides you with the ability to set your business logic without the boilerplates.

Advantages and Disadvantages of Python and Java

Java and Python are among the most widely used languages in the world (see Figure 1 below).

Both languages have their strengths and weaknesses and are popular in different fields. Unlike other articles, such as those from  Tom Radcliffe which analyzes which language is technically better implemented, this article focuses on presenting practical use cases with explicit examples. Let us check the following table that provides a brief overview, of which language is best suited for which field (✅ = advantage, and ❌ = disadvantage). 

IT systems need integration to achieve seamless data flow alongside enhanced operational efficiency. The expansion of businesses creates independent operational systems that restrict performance through object isolation and restrict time-sensitive information acquisition. The system's functions become oriented for better workflow coordination, which minimizes both repetition and creates unified operations.

The creation of such connections necessitates comprehensive knowledge about technical and business needs, which include format patterns along with protocol standards. Java provides robust libraries alongside outstanding frameworks that lead organizations to choose Java when building scalable, customized solutions. A strategically developed connector fulfills present requirements while enabling future technology adjustments, thus becoming a sustainable factor that supports successful IT system integration.

All objects in Java implicitly inherit from java.lang.Object. This class contains multiple methods, which can be overridden in the child class. 

One such overridable method is finalize(). Before objects get garbage collected from memory, the JVM will execute the finalize(). So, if you need to close any resources that were opened in the class (like backend connections, Files…), it can be done in this method. 

Why GraphQL?

GraphQL provides a powerful layer to unify data from various backend sources, including databases, REST APIs, and microservices, into a single, consistent API. It enables the creation of flexible APIs that can evolve with changing client applications.

Introduction

This article will show you how to create an effective application that implements GraphQL using the Netflix DGS framework in the Spring Boot application.
