My doubt is simple, I believe. I need to call this interface CadastroGUI d = new CadastroGUI(); which I already have ready, but I want the fields already appear filled, after all, is a query command by CPF where I want to return the customer information.

The Code

public void actionPerformed(ActionEvent arg0) {

                String cpf = txtCPF.getText();

                DaoCadastro c = new DaoCadastro();
                ArrayList <Cadastro> co = new ArrayList <Cadastro>();

                CadastroGUI d = new CadastroGUI();
                d.setVisible(true);

                co = c.listaAlterar(cpf);
                int a=0;

                for (a=0; a<co.size();a++)

                {
                    txtNome.setText (co.get(a).Nome);
                    txtCPF.setText (co.get(a).CPF);
                    txtEndereco.setText(co.get(a).Endereco);
                    txtSexo.setText(co.get(a).Sexo);
                    txtDataNasc.setText (co.get(a).Datanasc);



            }
java interface

  • You call Cadastrogui another screen and want it to be filled with information from the previous screen?

  • I have the template Registration ready, so I want to make a query through the CPF in another interface, call the Registration when filling the CPF and press a jbutton procurar and receive the information already setadas in the register that will be called

  • When I put this Cadasgui d = new Cadastrogui(); d.setVisible(true); it is coming, but it is not filled. I want it to be filled with the information that is connected to the CPF that I will look for.

  • This information comes from the screen that calls Cadasgui or you already bring direct from the bank?

    careful when using the word interface in this way, in java it has another meaning. How do you send the information to Cadastrogui? it is a Jframe?

  • What @Skywalker said is true. I suggest you edit the question title to "graphical interface" since we’re talking about GUI’s.

  • I am learning more and more from you because I am a beginner in kk programming. I bring from the bank @Diegofelipe.

  • It’s Jframe yes @Skywalker, the information filled in in Jtextfields.

  • send the information you want to display in Cadastrogui by a constructor. Build a constructor in Cadastrogui.

Create another constructor in Cadasgui with parameter for your arraylist: 

    CadastroGUI(ArrayList<Cadastro> co)
    {
        CadastroGUI();
        //aqui você faz o preenchimento dos campos.
        int a=0;
        for (a=0; a < co.size(); a++)
        {
            txtNome.setText (co.get(a).Nome);
            txtCPF.setText (co.get(a).CPF);
            txtEndereco.setText(co.get(a).Endereco);
            txtSexo.setText(co.get(a).Sexo);
            txtDataNasc.setText (co.get(a).Datanasc);
        }
    }

And in your event you simply call it by passing the arraylist by parameter:

    public void actionPerformed(ActionEvent arg0) 
    {
        String cpf = txtCPF.getText();
        DaoCadastro c = new DaoCadastro();
        ArrayList <Cadastro> co = new ArrayList <Cadastro>();
        co = c.listaAlterar(cpf);
        CadastroGUI d = new CadastroGUI(co);
        d.setVisible(true);
    }
