## Overview

ACMETech is a Java Swing application for brokering technology sales. Its startup loads participant, technology, and sales input data into catalogs; users then manage suppliers, technologies, buyers, and sales, consult rankings and view reports, and save or reload catalog data as CSV or JSON. The graph includes documented capabilities whose wiring was not fully sampled, using the existing GUI directory where specific screen calls were not verified.

Main entry points: [`src/interfaceGrafica`](https://github.com/douglasilvano/tf_poo/tree/main/src/interfaceGrafica) (Swing screens), [`src/entidades/CatalogoTecnologias.java`](https://github.com/douglasilvano/tf_poo/blob/main/src/entidades/CatalogoTecnologias.java) (Technology catalog), [`src/aplicacao/ACMETech.java`](https://github.com/douglasilvano/tf_poo/blob/main/src/aplicacao/ACMETech.java) (Startup loader), [`src/entidades/CatalogoCompradores.java`](https://github.com/douglasilvano/tf_poo/blob/main/src/entidades/CatalogoCompradores.java) (Buyer catalog)
