I am trying to setup an array of buttons and have a sound play when each button is selected. I have the button array displaying, but cannot get the sound to play when a button is selected (the synthesizer class is provided and I call the class passsing (note, instrument, duration). However, I never appear to got to the actionPerformed method of button (that I set up). Can anyone provide any help? The followining is my code:
package unit2;
// import Swing package to support Components
import javax.swing.*;
// import awt package for the Container class, in support of the Content Pane
import java.awt.*;
// import event package
import java.awt.event.*;
class Events extends JFrame implements ActionListener {
// declare the JButton component as an attribute
JButton[] buttons;
int i;
// create constructor with no arguments
public Events ( ) {
super ( );
init ();
}
// create constructor with
string argument for the frame's title
public Events (String title) {
super (title);
init ();
}
// create the init method to initialize the application
public void init ( ) {
Container c = this.getContentPane ();
c.setBackground(Color.white);
c.setLayout (new GridLayout (8, 16, 5, 5));
buttons = new JButton [128];
for ( int i = 0; i < 128; i++) {
buttons[i] = new JButton ("" + i);
c.add (buttons[ i ]);
buttons[i].addActionListener(this) ;
}
this.setSize (1000, 500);
this.setVisible ( true );
this.setDefaultCloseOperation ( JFrame.EXIT_ON_CLOSE );
}
public void actionPerformed (ActionEvent e) {
SynthPlayer syn = new SynthPlayer();
int count;
for(count = 0; count < 128; count++) {
if(e.getSource() == buttons[count])
syn.playNote(50, count, 1000);
// System.exit is necessary when working with the synth
System.exit(1);
}
}
// main method that creates a GridAssign
public static void main(String[] args) {
Events g = new Events ("Assignment
Unit 2 - EVENTS");
