## Overview
Aulas_Java is a collection of standalone Java course examples and exercises, not a single application. The visible workflows are console input, a small lesson-specific calculation or object operation, and printed results. The README describes broader Java, JavaFX, database, and Spring topics, but those implementations are not present in this tree; the graph therefore focuses on the source-backed lessons. Edges reflect the excerpts and SOURCE INDEX references; unsampled behavior is not inferred.
