Extract values from given Form

Question

I want to extract values on clicking the button save. Extract values from JTextField and JTable rows and columns. Just want a rough idea how to do extract and save values in different variables. I want to do these saving actions under the button save.

In addition to invoking textField.getText(), you can obtain a reference to your table's model and iterate over the values using getValueAt():

JButton save = new JButton("Save");
save.addActionListener(new ActionListener() {
    @Override
    public void actionPerformed(ActionEvent e) {
        System.out.println(textField.getText());
        TableModel model = table.getModel();
        for (int r = 0; r < model.getRowCount(); r++) {
            for (int c = 0; c < model.getColumnCount(); c++) {
                System.out.print(model.getValueAt(r, c) + " ");
            }
            System.out.println();
        }
    }
});

From the jtextfield you can invoke the getText method to get the contents of the textfield in the form of a String like:

String myString = textField.getText();

From JTable use getValueAt method to retrieve the value.

From JTextField use textField.getText() as stated by @Abu
