NetBeans compila mas não mostra a tela

Tyeska · Julho 24, 2012, 9:32am

Olá, estou iniciando no mundo java, e já criei 2 projeto: uma calculadora e um desenho.
O meu problema é que quando utilizo shift+F6 ele me mostra meu trabalho sem problemas. Porém quando vou compilar usando F6, ele compila sem problemas mas não me mostra a Tela do projeto compilado. O que estou fazendo errado???
Utilizo o NetBeans 7.1.2 e windows7. Desde já agradeço a todos.

Você está rodando esta classe (shift + F6) ou rodando o projeto (F6)?

Tyeska · Julho 24, 2012, 2:41pm

Se eu aperto shift+F6 exibe a Tela do Projeto sem Problemas.

Mas quando dou alt+F6 ou apenas F6, mostra compilado com sucesso, porém a tela do projeto não exibe.

Gostaria que assim q eu aperta-se o F6, meu projeto compila-se e fosse exibido de forma funcional, como um programa de verdade.

Pois quando olho tutoriais, o pessoal aperta o F6 e o projeto é compilado e a tela do projeto aparece. Mas no meu isso não acontece. O que estou fazendo de errado??

O que acontece é que o NB cria uma classe principal, que é a classe definida por ele como sendo a main class do projeto.
Logo, ao pressionar F6, você compila e executa o jar gerado, cuja main class é a classe definida pelo NB, que, caso você não tenha alterado, irá possuir um método main vazio.
Encontre essa classe e faça algo como

public static void main(String[] args){
   new JFCalc().setVisible(true);
}

Que o problema deve se resolver.

Leeegggallll!!!
Funcionou, muito obrigada. Agora finalmente meus projetos vão rodar com F6 kkkkk.
Valeu por compartilhar sua experiencia, espero que meu problema seja util para mais pessoas.
