Telegram Bot Java Library is a Java library for building bots that interact with Telegram's Bot API.
The library abstracts away the complexity of communicating with Telegram's servers, allowing developers to focus on bot logic rather than HTTP plumbing. It supports both webhook and long polling approaches for receiving updates, though the maintainer recommends long polling. The library handles message sending, file uploads, custom keyboards, inline query support, and other core Telegram bot features through a straightforward API.
Developers building Telegram bots in Java should choose this library if they want a lightweight, simple-to-use wrapper around the official Telegram Bot API. It works well for bots of any complexity, from basic message responders to bots with custom keyboards and file handling. The project includes example bots demonstrating various capabilities such as weather information, directions, file management, language support, and webhook integration, with their source code available separately for reference.
The project accepts pull requests against the development branch when they add meaningful functionality. The maintainer actively manages contributions and has established a clear policy against accepting code containing API tokens or keys. A dedicated Telegram chat channel exists for questions and suggestions, providing a direct communication channel for users seeking help or wanting to propose improvements.
