Best java libraries of 2017

Let’s highlight Best Java libraries of 2017. this list highlights new & innovative Java libraries. These libraries contain packages which extend functionalities of Java applications. they had an explosion in their popularity as compared to traditional java libraries.

1 – spring Boot

Spring Boot covers your basic configuration & the general dependencies.  It takes an opinionated view of the Spring platform so that new and existing users can quickly get to the bits they need. You can use Spring Boot to create stand-alone Java applications that can be started using java -jar or more traditional WAR deployments.





why Best?

  •  you get a lot of things out of the box like metrics, content negotiation, marshaling, caching, social features, etc.
  • provides Typesafe configuration to govern and validate configuration properties.
  • It is Best for rapid web app testing and development.
  • It can be integrated with almost any technology like a relational database, MongoDB, Redis, JMS, etc.
  • You don’t need a servlet container or an application server.

 2 –  RxJava  – Reactive Extensions for the JVM

RxJava is a Java VM implementation of Reactive Extensions: a library for composing asynchronous and event-based programs by using observable sequences. RxJava is a mature open source library that has found broad adoption both on the server and on Android mobile devices.


why Best?

  • RxJava Observables can be composed instead of nested, saving the developer from the callback hell
  • RxJava offers dozens of operators that allow composing, transforming, scheduling, throttling, error handling, and lifecycle management.
  • composes asynchronous and event-based programs
  • offers virtual time and schedules for parameterized concurrency

 3 –  Guava: Google Core Libraries for Java

Guava is a set of core libraries that includes new collection types (such as multimap and multiset), immutable collections, a graph library, functional types, an in-memory cache, and APIs/utilities for concurrency, I/O, hashing, primitives, reflection, string processing, and much more!

why Best?

  • Ordering is great for building Comparator that behaves just how you want
  •  It facilitates best coding practices and helps reduce coding errors.
  • it provides utility methods for collections, caching, primitives support, concurrency, common annotations, string processing, I/O, and validations.

4 – Ok Http

OkHttp perseveres when the network is troublesome: it will silently recover from common connection problems. If your service has multiple IP addresses OkHttp will attempt alternate addresses if the first connect fails. HTTP is the way modern applications network. It’s how we exchange data & media. Doing HTTP efficiently makes your stuff load faster and saves bandwidth.


why Best?

  • HTTP/2 support allows all requests to the same host to share a socket.
  • Connection pooling reduces request latency (if HTTP/2 isn’t available).
  • Transparent GZIP shrinks download sizes.
  • Response caching avoids the network completely for repeat requests.

Information & Popularity

An HTTP+HTTP/2 client for Android and Java applications.

5 – Spring Framework

The Spring Framework provides a comprehensive programming and configuration model for modern Java-based enterprise applications — on any kind of deployment platform. A key element of Spring is infrastructural support at the application level: Spring focuses on the “plumbing” of enterprise applications so that teams can focus on application-level business logic, without unnecessary ties to specific deployment environments.

spring framework

why Best?

  • Spring framework provides templates for JDBC, Hibernate, JPA etc. technologies.
  • The Dependency Injection makes easier to test the application
  • The Spring Framework doesn’t force the programmer to inherit any class or implement any interface.
  • It provides a powerful abstraction to JavaEE specifications such as JMS, JDBC, JPA, and JTA.
  • It provides declarative support for caching, validation, transactions, and formatting.
