## Overview

This repository is a collection of Java learning exercises, not a single full-stack application. The clearest runtime workflows are servlet-based login handling, command-line JDBC operations, Hibernate persistence, and serialization; the tree also contains form and language exercises. The README describes broader JSP, Spring, REST, and related curriculum, but those implementations are not represented in the supplied tree, so they are not mapped as runtime components. Connections are limited to relationships visible in excerpts or the source index.
