如何用Java在Midi文件中列出乐器名称？

import javax.sound.midi.*;

public class MidiInstrumentList {
    public static void main(String[] args) {
        try {
            // 创建一个Sequencer对象
            Sequencer sequencer = MidiSystem.getSequencer();
            sequencer.open();

            // 读取MIDI文件
            Sequence sequence = MidiSystem.getSequence(new File("example.mid"));

            // 获取所有的Track
            Track[] tracks = sequence.getTracks();

            // 遍历每个Track
            for (int i = 0; i < tracks.length; i++) {
                Track track = tracks[i];
                System.out.println("Track " + i + ":");

                // 遍历每个MIDI事件
                for (int j = 0; j < track.size(); j++) {
                    MidiEvent event = track.get(j);
                    MidiMessage message = event.getMessage();

                    // 检查是否为音符消息
                    if (message instanceof ShortMessage) {
                        ShortMessage sm = (ShortMessage) message;

                        // 获取乐器编号
                        int instrument = sm.getData1();

                        // 获取乐器名称
                        String instrumentName = getInstrumentName(instrument);

                        System.out.println("Event " + j + ": " + instrumentName);
                    }
                }
            }

            sequencer.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    // 获取乐器名称
    public static String getInstrumentName(int instrument) {
        String[] instrumentNames = {
            "Acoustic Grand Piano", "Bright Acoustic Piano", "Electric Grand Piano", "Honky-tonk Piano",
            "Electric Piano 1", "Electric Piano 2", "Harpsichord", "Clavi", "Celesta", "Glockenspiel",
            // 其他乐器名称...
        };

        if (instrument >= 0 && instrument < instrumentNames.length) {
            return instrumentNames[instrument];
        } else {
            return "Unknown";
        }
    }
}
