At first, you need to check your GUI, because from skimming it works not good. Later you can get data from the different component using an appropriate listener for each component or you can use any General button to reading data from all components and print it in a console or anywhere else. To get data from combo, for example, will be here:

String data = combo.getSelectedIndex();

More information you can get here: How can I get the user input in Java?

You need to use listeners to create code that runs when ui component is pressed. I added listener to every component. try it:

public class UI extends JFrame {
    public static void main(String[] args) {
        JFrame frame = new JFrame();
        frame.setSize(500, 600);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        BorderLayout blayout = new BorderLayout();
        JButton center = new JButton();
        JButton north = new JButton();
        JButton south = new JButton();
        south.addActionListener(e->{System.out.println("Save button is pressed");});
        JComboBox combo = new JComboBox();
        combo.addItem("-");
        combo.addItem("Tehran");
        combo.addItem("Tabriz");
        combo.addItem("Shiraz");
        combo.addActionListener(e -> {
            System.out.println(((JComboBox<String>) e.getSource()).getSelectedItem());
        });
        JRadioButton rb1 = new JRadioButton("man");
        rb1.addActionListener(e -> {
            System.out.println("man: " + ((JRadioButton) e.getSource()).isSelected());
        });
        JRadioButton rb2 = new JRadioButton("weman");
        rb2.addActionListener(e -> {
            System.out.println("weman: " + ((JRadioButton) e.getSource()).isSelected());
        });
        frame.setLayout(blayout);
        FlowLayout fLoyout = new FlowLayout(FlowLayout.CENTER);
        center.setLayout(fLoyout);
        south.setLayout(fLoyout);
        JLabel jb1 = new JLabel("Name :");
        JTextField name = new JTextField(20);
        center.add(jb1);
        center.add(name);
        name.addActionListener(e -> {
            System.out.println("name: " + ((JTextField) e.getSource()).getText());
        });
        JLabel jb2 = new JLabel("Family :");
        JTextField family = new JTextField(20);
        center.add(jb2);
        center.add(family);
        family.addActionListener(e -> {
            System.out.println("family: " + ((JTextField) e.getSource()).getText());
        });
        JLabel jb4 = new JLabel("City :");
        center.add(jb4);
        center.add(combo);
        JLabel jb5 = new JLabel("Sex :");
        center.add(jb5);
        center.add(rb1);
        center.add(rb2);
        JLabel jb6 = new JLabel("Comment :");
        JTextField comment = new JTextField(50);
        comment.addActionListener(e -> {
            System.out.println("comment: " + ((JTextField) e.getSource()).getText());
        });
        JLabel jb7 = new JLabel("Save");
        south.add(jb7);
        JPanel cpanel = new JPanel();
        cpanel.add(center);
        JPanel spanel = new JPanel();
        spanel.add(south);
        cpanel.setLayout(new BoxLayout(cpanel, BoxLayout.Y_AXIS));
        cpanel.add(jb6);
        cpanel.add(comment);
        frame.add(cpanel, BorderLayout.CENTER);
        frame.add(spanel, BorderLayout.SOUTH);

        frame.pack();
        frame.setVisible(true);
    }
}

You will have to put JRadioButton into RadioGroup to select one of them.

thank you but i have problem with Jtextfield because i can see them at console . but other thing runs ok . — alish, Apr 27 '17 at 06:27
