guava vs Web3j: What are the differences?
Developers describe guava as "Google Core Libraries for Java 6+". 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. On the other hand, Web3j is detailed as "Lightweight Java and Android library for integration with Ethereum clients". It is a lightweight, highly modular, reactive, type safe Java and Android library for working with Smart Contracts and integrating with clients (nodes) on the Ethereum network. This allows you to work with the Ethereum blockchain, without the additional overhead of having to write your own integration code for the platform.
guava and Web3j can be primarily classified as "Java" tools.
guava is an open source tool with 35K GitHub stars and 7.83K GitHub forks. Here's a link to guava's open source repository on GitHub.
