estoy poniendome conjava un poco y tratando de aprender.
alguien me podria dar una mano para ver con un ej simple como el que estoy haciendo como puedo cerrar una ventana creada en java?
import java.awt.*;
import java.awt.event.*;
public class Calcu_1 implements WindowListener {
private Frame marco;
private Button suma;
private TextField numeroUno;
private TextField numeroDos;
public Calcu_1 (){
marco = new Frame ("Calcuadora sumadora");
suma = new Button("+");
numeroUno = new TextField ();
numeroDos = new TextField ();
}
public void abrirFrame (){
marco.setSize(150,150);
marco.setBackground (Color.blue);
marco.setLayout (new FlowLayout ());
marco.add(suma);
marco.add(numeroUno);
marco.add(numeroDos);
marco.pack();
marco.setVisible(true);
}
public void windowActivated (WindowEvent we){}
public void windowClosed (WindowEvent we){}
public void windowClosing (WindowEvent we){}
public void windowDeactivated (WindowEvent we){}
public void windowDeiconified (WindowEvent we){}
public void windowIconified (WindowEvent we){}
public void windowOpened (WindowEvent we){}
public static void main (String args[]){
Calcu_1 guiWindow = new Calcu_1();
guiWindow.abrirFrame();
}
}
