Hey there, I've been trying to get this code to work

Spoiler

import javax.sound.midi.*;


public class MiniMiniMusicCmdLine {   // this is the first one
       
     public static void main(String[] args) {
        MiniMiniMusicCmdLine mini = new MiniMiniMusicCmdLine();
        if (args.length < 2) {
            System.out.println("Don't forget the instrument and note args");
        } else {
            int instrument = Integer.parseInt(args[0]);
            int note = Integer.parseInt(args[1]);
            mini.play(instrument, note);
            
        }
     }

    public void play(int instrument, int note) {

      try {
 
         Sequencer player = MidiSystem.getSequencer();         
         player.open();
        
         Sequence seq = new Sequence(Sequence.PPQ, 4);         
         Track track = seq.createTrack();  
          
         MidiEvent event = null;

         ShortMessage first = new ShortMessage();
         first.setMessage(192, 1, instrument, 0);
         MidiEvent changeInstrument = new MidiEvent(first, 1); 
         track.add(changeInstrument);

         
         ShortMessage a = new ShortMessage();
         a.setMessage(144, 1, note, 100);
         MidiEvent noteOn = new MidiEvent(a, 1); 
         track.add(noteOn);

         ShortMessage b = new ShortMessage();
         b.setMessage(128, 1, note, 100);
         MidiEvent noteOff = new MidiEvent(b, 16); 
         track.add(noteOff);
         player.setSequence(seq); 
         player.start();
         // new
	     Thread.sleep(5000);
	     player.close();
         System.exit(0);

      } catch (Exception ex) {ex.printStackTrace();}
  } // close play

} // close class

I first typed it up on my own and finally copied and pasted the code and I get "Don't forget the instrument and note args"
If I'm not mistaken I DO have less than 2 arguments in my code thank you very much.
It wont let my type in the string for the instrument or note . Can anyone help me?

What are you typing at the command line to run the program?

>I DO have less than 2 arguments

If you have less than 2 arguments you will get that message. You need to supply 2 arguments.

eg:

F:\>java MiniMiniMusicCmdLine 102 30

F:\>java MiniMiniMusicCmdLine 102 30

It wont LET me put anything. I run it and it just gives that line nothing else. There is no, MiniMiniMusicCmdLine. Just
"Don't forget the instrument and note args"
But what I mean is that I do have 2 arguments in my CODE not in the command line. Sorry for not clarifying.

Yes, but how do you run it?

Add this code to the end of the try block...
After player.start();

Thread.sleep(2000);
player.close();
System.exit(0);
