amigos necesito una pista de como hacer para meter un evento a un boton.
!!!!!!!!!!!!!!!!!!!!Tengo la clase base:!!!!!!!!!!!!
package Instrumentos;
import java.io.*;
import java.util.*;
abstract class Instrumento {
protected String notas;
protected String clave;
public Instrumento(String notas,String clave) {
this.notas=notas;
this.clave=clave;
}
public void setNotas(String notas){
this.notas=notas;
}
public String getNotas(){
return notas;
}
public void setClave(String clave){
this.clave=clave;
}
public String getClave(){
return clave;
}
abstract String conversion();
public String leerGrafico()
{
File f;
javax.swing.JFileChooser j= new javax.swing.JFileChooser();
j.showOpenDialog(j);
String path= j.getSelectedFile().getAbsolutePath();
String lectura="";
f = new File(path);
try{
FileReader fr = new FileReader(f);
BufferedReader br = new BufferedReader(fr);
String aux;
while((aux = br.readLine())!=null)
lectura = lectura+aux+"\n";
}catch(IOException e){}
return lectura;
}
}
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!la subclase!!!!!!!!!!!!!!!!!!!

!!!!!!!!!!!!!!!!!!!!!!!!!!HAORA AKI MI PROBLEMA!!!!!!!!!!!!!!!!!!!!!
esta es la clase ventana
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JTextField;
import javax.swing.JButton;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
import javax.swing.*;
public class Ventana extends JFrame {
private JButton boton,boton2,boton3,boton4,boton5,boton6,boton7;
private JLabel nombre;
private JTextField op;
public Ventana() {
boton=new JButton("Trompeta");
boton2=new JButton("Tuba");
boton3=new JButton("Sax Alto");
boton4=new JButton("Sax Tenor");
boton5=new JButton("Corno");
boton6=new JButton("Trombom");
boton7=new JButton("Cancelar");

setLayout(null);
add(boton);
boton.setBounds(30,80,100,40);
add(nombre);
nombre.setBounds(160,40,80,80);
nombre.setSize(200,10);
add(boton2);

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Manejadorvent manejador=new Manejadorvent();
boton.addActionListener(manejador);
}
public class Manejadorvent implements ActionListener{
public void actionPerformed(ActionEvent e){
}}
public static void main(String args[]){
final Ventana Miventana=new Ventana();
Miventana.setVisible(true);
Miventana.setSize(500,400);
Miventana.setTitle("UNIVERSAL SPEED NOTAS");
}
}
como le agrego lo que tiene el case 1 a el primer boton porque ya no tendria chiste el menu en la clase main si ya los puse en la ventana?
