Tutorial Contents

okay, on this occasion I will create a java program for music player on netbeans, here I will create a simple user interface that lets us add playlists, play music, and delete playlists button.

here are the steps:

• the first step you should do is create a new project on NetBeans.
  

---

• then create a new JFrame class on the project you have created.
• right click on the project and select new >> JFrame:
  

---

the next step is to design the GUI for our project

• create a design like in the picture below:
  

---

• then right click on the three buttons that we have created, change the text, and variable name:
  

---

1. Add Playlist variabel name : add
2. Play button variable name : play
3. Delete button variable name : del

---

create the button function :

• first enter this code under the package section

import javax.swing.DefaultListModel;
import javax.swing.JFileChooser;
import java.io.File;

• double click on the button we have design, then fill in the source code for the button to work
• below is the source code for button Add Playlist

JFileChooser fc = new JFileChooser();
    JFrame jf = new JFrame();
    int agree = fc.showOpenDialog(jf.add(fc));
    int position = jList1.getModel().getSize();
    if(agree == JFileChooser.APPROVE_OPTION){
        File file = fc.getSelectedFile();
        String text = file.getPath().toString();
        String[] txt;
        txt = new String[]{text};
        model.add(position, text);

• then enter the code for the Play button

 if(evt.getActionCommand().equalsIgnoreCase("play music")){
        String main =jList1.getSelectedValue().toString();
        try{
            mp3 =Manager.createPlayer(new URL ("D:\\data1.txt",null,main));
            mp3.star();
        }
        catch(Exception ex){}
        play.setText("stop");
    }
    if(evt.getActionCommand().equalsIgnoreCase("stop")){
        mp3.stop();
        play.setText("play music");
    }
}

• last enter code for Delete button

private void delActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
    int position = jList.getSelectedIndex();
    model.remove(position);
}

• Okay, all the code we have entered, then I will explain the function of the codes that we have entered above:
• this code we use because we use several different types of input

import javax.swing.DefaultListModel;
import javax.swing.JFileChooser;
import java.io.File;

• this is the variable for the Music queueDefaultListModel model = new DefaultListModel ();
• this is a variable to play music private Player mp3;
• this works for the music selection process JFileChooser fc = new JFileChooser ();
• this works to bring up the music selection dialog int int = fc.showOpenDialog (jf.add (fc));
• int position = jList1.getModel (). getSize (); function to set the queue position of music
• File file = fc.getSelectedFile (); variable to select the music file to be played.
• This serves to retrieve the file name String text = file.getPath (). toString ();.
• String [] txt; variable to hold the file name.
• This works to display the music queue jList1.setModel (model);
• this is the condition when music has not been played if (evt.getActionCommand (). equalsIgnoreCase ("play music")) {
• catch (Exception ex) {} is a variable for error handling.
• play.setText (" stop "); create function keys when music is paused.
• model.remove (position); functions when deleting music files.
• okay, I think it's enough for the source code explanation, then we will run the program.

---

we will run the program we have created.

• after running it will look like this, click the Add Playlist button
  

---

• then select music from your folder.
  

---

• then it will look like this, then press button Play then music will be executed in sequence in folder:
  

---

• Okay, after we run it will be heard the sound of music means our project has been successful, but if it has not turned up the music sound then you must check your source code carefully, there may be a wrong part during the process of typing.
• okay, the tutorial is over if there is a less obvious part you can ask in the comment field.
