12 Awesome Java Libraries for your next work

12 Awesome Java Libraries for your next work!

The programming world is always changing. New tools are being built, the old ones are being updated, the old ones are being depreciated. The main goal of a programmer is to write code that works, and to do it well and fast. But why spend time reinventing the wheel if there are already great open source libraries out there? One can easily lose track of how many new libraries pop up every day that aim to improve your development process in some way.

Here is a short list of some awesome Java libraries that you might not have heard about yet, but you definitely should check them out!

1. FasterXML/jackson: Serialize Java objects to JSON, or convert JSON back into Java objects.

2. Google/gson: A modern JSON library for Kotlin and Java. Very easy to use and makes your work easier with a simple API!

3. Square/retrofit: Type-safe HTTP client for Android and Java by Square, Inc.

4. JakeWharton/butterknife: Field and method binding for Android views which uses annotation processing to generate boilerplate code for you.

5. ReactiveX/RxJava: Reactive Extensions

If you’re a fan of Java and want to try out some of the latest and greatest Java libraries, then you’re at the right place. I’ve compiled a list of 12 awesome libraries that are definitely worth a look.

1. Google Guava ( https://github.com/google/guava ) – Provides collections, caching, primitives support, concurrency libraries, common annotations, string processing, I/O and more

2. log4j ( https://logging.apache.org/log4j/2.x/ ) – Logging API for Java

3. jmh ( http://openjdk.java.net/projects/code-tools/jmh/) – Micro-benchmarking framework for the JVM

4. Gson ( https://github.com/google/gson ) – A Java serialization library that can convert Java Objects into JSON and back

5. MyBatis ( http://www.mybatis.org/) – A simple yet powerful SQL mapping framework in Java

6. SpringBoot ( https://projects.spring.io/spring-boot/) – Makes it easy to create stand-alone, production-grade Spring based Applications that you can ”

The last few years have seen a great expansion in the number of libraries that are available to java developers. While there is a huge selection of open source libraries out there, they vary greatly in quality and usability. This article will highlight some of the best libraries from the past year or so and hopefully you will find something useful for your next project.


Javalin is a very lightweight web framework for java and Kotlin. It has a really nice routing DSL that makes writing HTTP servers intuitive and easy to read. There is also enough configuration options available for most use cases. If you need something with more features I would recommend looking at Spark or Spring Boot instead.

2.Dagger 2

Dagger 2 is a dependency injection library that uses code generation to create it’s dependency graph at compile time rather than runtime. This results in much faster startup times compared to other DI libraries like Spring which has to build it’s dependency graph at runtime (making it more difficult to configure). The downside of this approach is that your development cycle will be longer as you have to recompile each time you make changes to your graph structure.


Retrofit is one of the most popular HTTP clients on Android and now supports java

Java is one of the most popular programming languages in the world. It is used for building web and mobile applications, which make it a good choice for many developers. There is an abundance of libraries available to help you with your Java projects. Here are 12 of the top Java libraries that are important to learn and understand as a Java developer.

1: [Lombok](https://projectlombok.org/)

Lombok is an open source library that helps to reduce boilerplate code by using simple annotations to generate boilerplate code for you, so you don’t have to write it yourself. The library has been around since 2009 and is used by many companies such as Google, Amazon, and Twitter.

2: [Log4j](https://logging.apache.org/log4j/2.x/)

Log4j is a logging API which allows you to record log messages from your application in different ways, such as writing out to files, databases, or send emails based on logging thresholds you set within your application. The Log4j library has been around for more than 15 years and is still being improved today. It’s also an Apache project which means it’s well tested and maintained by a large community of developers worldwide.

If you are a Java developer, you should be using Maven. Maven makes it easy to build and deploy your project. It has a lot of features that can help you speed up development time. One of those features is the ability to create custom plugins.

You can create a new plugin in Eclipse by right-clicking on an existing Java project and selecting “New” -> “Other” -> “Maven Project”. Then, click on the “Create New Project From Existing Archetype” button and follow the instructions. When you select “Java Plugin”, it will automatically generate a pom.xml file that contains information about your plugin, including its dependencies and configurations. The next step is to add the following config to your pom.xml file:





Now you can use the mvn command line tool to compile and run your plugin: $ m

Visual Studio Code is a very popular tool for Java developers, and provides a rich set of features for Java projects. This blog post provides an overview on how to get started with Java projects in Visual Studio Code.

We will cover the following topics:

* Setting up VSCode for Java development
