Java 8 vs guava: What are the differences?

Java 8 and Guava are two popular libraries in the Java ecosystem, each offering unique features and functionalities for developers. It's essential to understand the key differences between Java 8 and Guava to make an informed decision on which library to use for a particular project.

Functional Programming Support: Java 8 introduced functional programming support through the addition of lambda expressions, streams, and the Optional class. Guava, on the other hand, provides a more limited set of functional programming features compared to Java 8.
Collection Utilities: Guava offers a rich set of utility classes for working with collections, such as the Immutable collections, Multimaps, and BiMap. Java 8 also provides enhanced features for working with collections, but the functionality offered by Guava is more comprehensive and specialized.
Null Handling: Guava provides utilities like Preconditions and Optional to handle null values more effectively. While Java 8 introduced the Optional class to address null pointer exceptions, Guava's null handling utilities are more robust and feature-rich.
Concurrency Support: Guava includes a wide range of concurrency utilities, such as ListenableFuture and RateLimiter, making it easier for developers to work with multi-threaded applications. Java 8, while offering CompletableFuture for asynchronous programming, lacks the breadth of concurrency utilities provided by Guava.
Functional Interfaces: Java 8 introduced functional interfaces like Function, Consumer, and Predicate to enable functional programming paradigms. Guava also offers similar functional interfaces, but the naming conventions and implementations may vary slightly from those in Java 8.
Compatibility and Dependencies: Java 8 is part of the standard Java Development Kit (JDK), making it readily available for all Java developers. Guava, on the other hand, requires an additional dependency to be included in the project, which may affect the size and complexity of the project.

In Summary, understanding the key differences between Java 8 and Guava, such as functional programming support, collection utilities, null handling, concurrency support, functional interfaces, and compatibility, is crucial for selecting the right library for a Java project.

Detailed Comparison

guava	Java 8
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.	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.

What are some alternatives to guava, Java 8?

Quarkus

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.

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.

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

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

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

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

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

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

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

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.
