Java-docs-samples is a collection of code samples demonstrating Google Cloud Platform services, written in Java and Kotlin.
The repository serves as a reference implementation library for developers learning to integrate Google Cloud services into Java applications. It provides working examples across multiple GCP products including App Engine, authentication, AutoML, CDN, translation, video processing, and vision APIs. Each sample is designed to be self-contained and directly runnable, with setup instructions covering Java environment configuration, credential management through Application Default Credentials, and authentication flows.
Developers should use this repository when learning GCP service integration patterns or when seeking verified, production-ready code snippets for specific Google Cloud APIs. The samples are particularly valuable for teams adopting GCP services in Java-based projects, as they demonstrate idiomatic usage patterns and proper credential handling. The repository is most useful as a reference during development rather than as a library to be imported; samples are meant to be adapted for specific use cases. Some samples include accompanying guides on cloud.google.com that provide additional context.
The project maintains compatibility across multiple Java runtimes, with all changes required to pass testing on Java 11 and Java 17 before merging. Periodic validation occurs on Java 8 and Java 21 environments, though failures on these versions do not block contributions. The repository enforces consistent licensing headers across all source files and provides clear contribution guidelines for those submitting new samples or improvements.
