Los codigos fuentes de ejemplo estan mal, les dejo los corregidos ya probados en netbeans y eclipse, si jalan.

Ejemplo 1 de ventana

package clases;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import javax.swing.JFrame;
/**
* @author ESAD
*/
public class EjemploEventos {
public static void main (String[] args){
JFrame frame = new JFrame("Ejemplo de eventos ventanita");
frame.setLocation(100, 100);
frame.setVisible(true);
frame.addWindowListener(new WindowAdapter() {
@Override
public void windowClosing(WindowEvent e){
System.exit(0);
}
});
}
}

Ejemplo de código 2. Evento clic en un botón

Codigo corregido, digo si saben que tenemos poco tiempo, ¿porque la jaladita de que te ponen el codigo mal?

package clases;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import javax.swing.JButton;
import javax.swing.JFrame;
/**
* @author ESAD
*/
public class EjemploEventoRaton {

public static void main (String[] args){
JButton boton = new JButton("Oprime");
boton.setVisible(true);
boton.setSize(50, 50);
boton.setLocation(100,100);
JFrame frame=new JFrame("Ejemplo de eventos");
frame.setLocation(200, 200);
frame.setVisible(true);
frame.setSize(300, 300);
frame.add(boton);
boton.addMouseListener(new MouseAdapter() {

@Override
public void mouseClicked(MouseEvent e){
System.out.print("Diste clic en el boton Oprime");
}
});
frame.addWindowListener(new WindowAdapter() {

@Override
public void windowClosing(WindowEvent e){
System.exit(0);
}
});
}
}

Ejemplo de código 3. Evento de teclado en una caja de texto.

package clases;
import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import javax.swing.JFrame;
import javax.swing.JTextField;
/**
* @author ESAD
*/
public class EjemploEventoTeclado {
public static void main (String[] args){
JTextField cajaTexto= new JTextField("Etiqueta");
cajaTexto.setVisible(true);
cajaTexto.setSize(50, 50);
cajaTexto.setLocation(100,100);
JFrame frame = new JFrame("Ejemplo de eventos corregido");
frame.setLocation(200, 200);
frame.setVisible(true);
frame.setSize(300, 300);
frame.add(cajaTexto);
cajaTexto.addKeyListener(new KeyAdapter() {
@Override
public void keyPressed(KeyEvent e){
metodoAccion();
}
});
frame.addWindowListener (new WindowAdapter() {
@Override
public void windowClosing(WindowEvent e){
System.exit(0);
}
});
}

protected static void metodoAccion() {
// TODO Auto-generated method stub

}
}
