Answer 1

To update a frame's title, call setTitle:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class TitleUpdater {
    public static void main(String[] args) {
        final JFrame f = new JFrame("TitleUpdater");
        JButton btn = new JButton("press here");
        btn.addActionListener(new ActionListener(){
            int count = 0;
            public void actionPerformed(ActionEvent evt) {
                ++count;
                f.setTitle("pressed: " + count + " times.");
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.getContentPane().add(btn, BorderLayout.NORTH);
        f.setSize(400,100);
        f.setLocationRelativeTo(null);
        f.setVisible(true);
}
