JFrame Console Scanner – Photoshop

I have this app that runs in eclipse’s console and I want it to run in a jframe.
By that I mean that I want it to ask for name, a and b on the JFrame window and then write something on a file.

It works perfectly in the console but I don’t know how to run it as a JFrame.

I want it to look something like this(Image made in photoshop):

And then automaticaly close

Thanks in advance!

some imports...(trying to save space)

public class Test {

    public static void main(String[] args) throws FileNotFoundException,IOException {

    Scanner s = new Scanner(System.in);
    String fileName = new SimpleDateFormat("dd-MM-yyyy_HH-mm'.txt'").format(new Date());
    String obs;
    String name;
    String path = "some path";
    int a = 0, b = 0, c = 0, d = 0;
    System.out.println("input file name");
    name = s.nextLine();
    System.out.println("input a");
    a = s.nextInt();
    System.out.println("input b");
    b = s.nextInt();
    obs = s.nextLine();
    if (a >= 100) {
        d = a / 100;
        c = a % 100;
        b = c;
        a = a + d;
    }
    File file;
    if (StringUtils.isBlank(name)) {
        file = new File(path + fileName);
    } else {
        file = new File(path + name + "#" + fileName);
    }

    FileWriter writer = null;
    try {
        writer = new FileWriter(file);
        writer.write("something");

        if (StringUtils.isBlank(obs)) {
            writer.write("something");
        } else {
            writer.write(obs + "n");
        }
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        if (writer != null)
            try {
                writer.close();
            } catch (IOException ignore) {
            }
    }

}
}

    What you’ll need to do

    • separate out your core logic into a separate method that takes String name, int a, int b, ideally in a separate class – then you can reuse from your console version
    • Create a basic GUI in a frame with a button to kick off the process
    • listen to the button press and call core logic method
    • add validation of inputs if necessary
    • consider using JFileChooser to allow user to pick the file rather than having to type it in

    Example

    public class ConsoleInFrame {
    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                new ConsoleInFrame().showGui();
            }
        });
    }

    public void showGui() {
        JFrame frame = new JFrame();
        JTextField file = new JTextField(20);
        JTextField aText = new JTextField(4);
        JTextField bText = new JTextField(4);
        JButton go = new JButton("Go");

        JPanel panel = new JPanel();
        panel.setLayout(new GridLayout(3, 2));
        panel.add(new JLabel("File"));
        panel.add(file);
        panel.add(new JLabel("a"));
        panel.add(aText);
        panel.add(new JLabel("b"));
        panel.add(bText);

        frame.getContentPane().setLayout(
                new BoxLayout(frame.getContentPane(), BoxLayout.Y_AXIS));
        frame.getContentPane().add(panel);

        frame.getContentPane().add(go);

        go.addActionListener(new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) {
                process(file.getText(), Integer.parseInt(aText.getText()),
                        Integer.parseInt(bText.getText()));
            }
        });
        frame.pack();
        frame.setVisible(true);
    }

    public void process(String name, int a, int b) {
        String fileName = new SimpleDateFormat("dd-MM-yyyy_HH-mm'.txt'")
                .format(new Date());
        String obs;
        String path = "some path";
        int c = 0, d = 0;
        if (a >= 100) {
            d = a / 100;
            c = a % 100;
            b = c;
            a = a + d;
        }
        File file;
        if (StringUtils.isBlank(name)) {
            file = new File(path + fileName);
        } else {
            file = new File(path + name + "#" + fileName);
        }

        FileWriter writer = null;
        try {
            writer = new FileWriter(file);
            writer.write("something");

            if (StringUtils.isBlank(obs)) {
                writer.write("something");
            } else {
                writer.write(obs + "n");
            }
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (writer != null)
                try {
                    writer.close();
                } catch (IOException ignore) {
                }
        }

    }

    I think you could do something like this:

    enter image description here

    To do this you have to use JLabel to display text: https://docs.oracle.com/javase/tutorial/uiswing/components/label.html

    Then to get the input use JTextField:
    https://docs.oracle.com/javase/tutorial/uiswing/components/textfield.html

    And if you want you can use a JButton after you write in the JTextField to save everything to the file:
