Olá pessoal!
Estou com problema na minha aplicação, estou fazendo uma atividade para meu curso que consiste em criar uma tela utilizando o swing, mas quando vou rodar o código não abre a tela para eu verificar se está tudo certo.
Obs.: Não aparece nenhum erro de compilação. BUILD SUCCESSFUL (total time: 1 second)
Alguém consegue me ajudar?
mostra o código. provavelmente vc n colocou nada no main()
public class Atividade3PSII {
public static void main(String[] args) {
Tela t = new Tela();
t.setVisible(true);
}
}
public class Tela extends javax.swing.JPanel {
public Tela() {
initComponents();
}
public Double qtde = 0.0;
public Double total = 0.0;
public Double media = 0.0;
public void calculoTotal(){
totalVotos.setText(""+total);
}
public void calcularMedia(){
media = total/qtde;
notaAtual.setText(""+media);
}
