Tenho dois botões entrar e sair. Como que eu faço comando para sair no JFRAME ? e sistema deverá mostrar todos os valores inseridos em uma janela gráfica e posteriormente apagar todas as informações nos componentes?

Vê se isso atende as suas necessidades!
Em algum ponto na sua tela principal:

JFrame minhaTela2 = new JFrame();
minhaTela2.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
minhaTela2.setVisible(true);

Cara, eu tenho que juntar duas telas e não estou conseguindo .

#4

No seu JButton1 quando permite o acesso chama a tela de cadastro como o @Jelson1 indicou.

#5

Eu vou tentar faze isso aqui

Alguém ajude me a resolver este exercício ? RESOLVER E NÃO FAZER, PRECISO APRENDER?
#6

O exercício é este, eu faltei de aulas por estar gripado. Se você puder me ajudar, ficarei grato

Primeira dúvida que eu tenho, a tela de Login e de Cadastro fica dentro do mesmo projeto ?

#9

Sim!

Sim, mas dependendo do tamanho do projetos você pode organizar os arquivos em subpastas, tipo uma pasta para guardar apenas imagens, etc, tudo isso dentro do seu projetos principal. Isso é muito relativo e vale mais apenas em projetos grande, eu acho que não é seu caso. Então você fez certo sim!

Por causa da minha gripe e do Corona Vírus, eu fiquei com medo de ir a aula. Próxima pergunta, Eu tenho o Botão de entrar, ele que chama a outra tela de Cadastro, é isso que o exercício pede ?

#13

Desenvolva um pequeno sistema que contemple as seguintes telas:
Tela de login
Número de telefone (JTextField)
Senha (JPasswordField)
Entrar (JButton)
Sair (JButton)
Eventos
Botão Salvar - o sistema deverá verificar se os conteúdos inseridos nos campos Número de telefone e Senha são iguais, se forem, o sistema deverá permitir o acesso do usuário na Tela de Cadastro de Livros. Se os conteú dos não forem iguais, o sistema deverá mostrar a seguinte mensagem “Telefone e/ou Senha inválidos! Tente novamente”. Após isso todos os dados deverãoser apagados nos componentes gráficos.

Sinceramente, eu fique na dúvida sobre a disposição das telas e se chamar um novo JFrame é a melhor solução. Mas acho que sim é no botão de entrar que chama a tela de cadastro.

Deu algum erro? Mostre o trecho do código em que você implementou isso!

Errro não deu, só não entra na segunda tela

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
if(txtTel.getText().equals(“1234”) && txtSen.getText().equals(“1234”))
{
JOptionPane.showMessageDialog(null,“Acesso Permitido”);
JFrame minhaTela2 = new JFrame();
minhaTela2.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
minhaTela2.setVisible(true);

  }else{
       JOptionPane.showMessageDialog(null,"Telefone ou Senha Inválidos,Tente Novamente!");
   }
}
#19

O exemplo que eu dei era genérico você tem chamar a sua tela:

TelaCadastro telaCadastro = new TelaCadastro();
telaCadastro.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
telaCadastro.setVisible(true);

Verifique se eu escrevi certo o nome da sua tela!

Como você vai mostra a tela de cadastro você não precisa mais desse trecho.
