#2

Pode ser erro de cache do NetBeans, clique com botão direito no projeto e na opção “limpar e construir” ou algo assim, depois tente executar. Se não funcionar, verifique se a classe Menu contem erros.

#3

Esse é o erro que esta dando.

#4

Se já fez o que sugeri, então tente apagar aquela linha Menu menu = new Menu(); e rescreva (caractere por caractere), pois pode conter algum caractere invisível que o compilador não reconheça, e depois execute.

Caso não funcione, tente reconstruir o projeto, crie um novo e copie as classes para este novo, pode ser algum problema na configuração do projeto.

#5

A classe Menu está no mesmo pacote que a classe Login?
Se não estiver, ela é pública? Está fazendo o import dela?

#6

Obrigado, consegui resolver o problema.

#7

E qual era o problema?
Mais gente pode estar passando pela mesma dificuldade.
