Olá Thiago, gostaria de um favor seu (preço a combinar $_$):
ResponderExcluirfazer um projeto de estacionamento de carros com array e joptionpane,
tipo criar algumas claases com atributos e metodos e uma classe main chamando essas classes criadas para rodar o programa
segue meu email : movalum@hotmail.com
Boa tarde:
ResponderExcluirMeu arquivo está igualzinho ao seu, porém o resultado só lê a última linha "grau 3 de obesidade"; se eu for apagando usará a resposta anterior e assim sucessivamente. O netbeans não acusa erro. Estou usando a versão 8.0.Você poderia me dizer onde está o erro? Maria Cristina
