直接添加一个音乐文件就行了
补充：
import javax.sound.midi.*;
class Test {
public static void main(String[] args) {
try {
Sequencer sequencer = MidiSystem.getSequencer();
sequencer.open();
Sequence seq = new Sequence(Sequence.PPQ, 4);
Track track = seq.createTrack();
for (int i = 5; i < 61; i++) {
track.add(makeEvent(144, 1, i, 100, i));
track.add(makeEvent(128, 1, i, 100, i + 2));
} // end loop
sequencer.setSequence(seq);
sequencer.setTempoInBPM(220);
sequencer.start();
quitProgram(sequencer);
}
catch (Exception ex) {
ex.printStackTrace();
}
} // end main
public static void quitProgram(Sequencer sequencer) {
while (sequencer.isRunning()) {
System.out.println("isRunning");
}
System.exit(0);
}
public static MidiEvent makeEvent(int comd, int chan, int one, int two,
int tick) {
MidiEvent event = null;
try {
ShortMessage a = new ShortMessage();
a.setMessage(comd, chan, one, two);
event = new MidiEvent(a, tick);
}
catch (Exception e) {
e.printStackTrace();
}
return event;
}
}
