Java 8 vs Quarkus: What are the differences?

Introduction

Java 8 and Quarkus are both popular technologies used in web development. While Java 8 is a programming language, Quarkus is a framework built on top of Java. In this article, we will explore the key differences between Java 8 and Quarkus.

  1. Execution Model: Java 8 follows a traditional execution model where applications are deployed as monolithic Java Virtual Machines (JVMs). On the other hand, Quarkus introduces a new SubstrateVM-based execution model, which allows for faster startup times and lower memory consumption.

  2. Microservices Architecture: Java 8 is primarily designed for building monolithic applications. In contrast, Quarkus is specifically designed for developing microservices-based applications. It provides features like dependency injection, configuration management, and reactive programming that are essential for microservices development.

  3. Hot Reload: Java 8 does not natively support hot reload, which means any changes made to the code require the application to be redeployed. Quarkus, on the other hand, offers hot reload functionality, allowing developers to instantly see their changes without the need for redeployment.

  4. Built-in Support for Cloud-Native Development: Quarkus is designed with cloud-native development in mind. It provides built-in support for popular cloud technologies like Kubernetes, OpenShift, and GraalVM. Java 8, on the other hand, requires additional configurations and dependencies to make applications cloud-ready.

  5. Memory Footprint: Quarkus optimizes memory usage by only loading the necessary runtime libraries and classes required for the application. This significantly reduces the memory footprint compared to Java 8, which typically loads the entire JVM, resulting in higher memory consumption.

  6. Developer Productivity: Quarkus offers a streamlined development experience with features like live coding, easy testing, and a comprehensive set of extensions. This improves developer productivity by allowing faster development and easier debugging. Java 8, while powerful, lacks some of these modern development features.

In summary, Quarkus introduces a new execution model, supports microservices architecture, offers hot reload functionality, provides built-in support for cloud-native development, optimizes memory usage, and enhances developer productivity. These differences make Quarkus a preferred choice for modern web application development compared to Java 8.

Detailed Comparison

Java 8

Quarkus
Quarkus

It is a revolutionary release of the world’s no 1 development platform. It includes a huge upgrade to the Java programming model and a coordinated evolution of the JVM, Java language, and libraries. Java 8 includes features for productivity, ease of use, improved polyglot programming, security and improved performance.

It tailors your application for GraalVM and HotSpot. Amazingly fast boot time, incredibly low RSS memory (not just heap size!) offering near instant scale up and high density memory utilization in container orchestration platforms like Kubernetes. We use a technique we call compile time boot.

What are some alternatives to Java 8, Quarkus?

MyBatis

MyBatis

It is a first class persistence framework with support for custom SQL, stored procedures and advanced mappings. It eliminates almost all of the JDBC code and manual setting of parameters and retrieval of results. It can use simple XML or Annotations for configuration and map primitives, Map interfaces and Java POJOs (Plain Old Java Objects) to database records.

guava

guava

The Guava project contains several of Google's core libraries that we rely on in our Java-based projects: collections, caching, primitives support, concurrency libraries, common annotations, string processing, I/O, and so forth.

Thymeleaf

Thymeleaf

It is a modern server-side Java template engine for both web and standalone environments. It is aimed at creating elegant web code while adding powerful features and retaining prototyping abilities.

JSF

JSF

It is used for building component-based user interfaces for web applications and was formalized as a standard through the Java Community

JavaMelody

JavaMelody

It is used to monitor Java or Java EE application servers in QA and production environments. It is not a tool to simulate requests from users, it is a tool to measure and calculate statistics on real operation of an application depending on the usage of the application by users. It is mainly based on statistics of requests and on evolution charts.

RxJava

RxJava

A library for composing asynchronous and event-based programs by using observable sequences for the Java VM.

MapStruct

MapStruct

It is a code generator that greatly simplifies the implementation of mappings between Java bean types based on a convention over configuration approach. The generated mapping code uses plain method invocations and thus is fast, type-safe and easy to understand.

Apache FreeMarker

Apache FreeMarker

It is a "template engine"; a generic tool to generate text output (anything from HTML to auto generated source code) based on templates. It's a Java package, a class library for Java programmers.

Jackson

Jackson

It is a suite of data-processing tools for Java (and the JVM platform), including the flagship streaming JSON parser / generator library, matching data-binding library (POJOs to and from JSON) and additional data format modules to process data encoded in Avro, BSON, CBOR, CSV, Smile, (Java) Properties, Protobuf, XML or YAML; and even the large set of data format modules to support data types of widely used data types such as Guava, Joda.

Project Reactor

Project Reactor

It is a fourth-generation Reactive library for building non-blocking applications on the JVM based on the Reactive Streams Specification. It is a fully non-blocking foundation with efficient demand management. It directly interacts with Java functional API, Completable Future, Stream and Duration.
