Programming with ServiceLoader API in Java

on YouTube ↗59m

" summary

Demonstrates using ServiceLoader with Java modules to build a plugin-style soft‑drink example (softdrink interface, Coke/DietCoke and Pepsi/DietPepsi modules compiled to JARs) and runs a client on the command line; shows module descriptors using module provides/uses instead of exports, uses java.util.ServiceLoader for dynamic discovery, supports factory/static provider methods for non‑default constructors, shows lazy instantiation and caching, a reload() option, and streaming providers so metadata (annotations/types) can filter implementations.
