LanguageProject Introduction
Summary
Guava is a set of core Java libraries from Google that includes new collection types, immutable collections, graph libraries, functional types, caching, and I/O utilities. It aims to improve code readability and efficiency in Java projects.
Problem Solved
Java's standard library, while robust, sometimes lacks convenient or high-performance implementations for common programming tasks. Guava fills these gaps by providing highly optimized, production-ready utilities and new data structures.
Core Features
Extended Collections Framework
Offers new collection types (multiset, multimap, etc.) and powerful utilities for existing ones, simplifying common collection operations.
Caching Utilities
Provides powerful caching utilities, including loading and expiring caches, essential for high-performance applications.
Utility Classes
Adds helpful utilities for working with Java primitives and common data structures, reducing boilerplate code.
Tech Stack

使用场景
Guava's versatile utilities are applicable across various Java project types, from backend services to desktop applications, wherever common programming patterns are used.
Scenario 1: Enhancing Data Structures
Details
Replacing standard Java collections with Guava's immutable or new types (like Multiset, BiMap) to simplify code and ensure data integrity.
User Value
Improves code clarity, reduces potential bugs related to mutable state, and provides specialized data structures.
Scenario 2: Implementing Application Caching
Details
Implementing caching logic using Guava's LoadingCache or CacheBuilder for frequently accessed data to reduce database load or computation time.
User Value
Significantly improves application performance and reduces latency for users.
