作了个定时器，怎么让他到时间了发声音出来啊

Answer 1

我用了thread，都弄好了，就是不会发声音

Answer 2

给你一段播放声音的代码学习一下：
import javax.sound.sampled.*;
import java.io.*;
import java.net.*;
 class PlaySound {
 
 
  public PlaySound(String pos) {
    try {
        // 创建一个你要播放的文件
        AudioInputStream stream = AudioSystem.getAudioInputStream(new File(pos));  //在此改成你的文件路径
        AudioFormat format = stream.getFormat();
        if (format.getEncoding() != AudioFormat.Encoding.PCM_SIGNED) {
            format = new AudioFormat(
                    AudioFormat.Encoding.PCM_SIGNED,
                    format.getSampleRate(),
                    format.getSampleSizeInBits()*2,
                    format.getChannels(),
                    format.getFrameSize()*2,
                    format.getFrameRate(),
                    true);        // big endian
            stream = AudioSystem.getAudioInputStream(format, stream);
        }        // Create line
        SourceDataLine.Info info = new DataLine.Info(
            SourceDataLine.class, stream.getFormat(),
            ((int)stream.getFrameLength()*format.getFrameSize()));
        SourceDataLine line = (SourceDataLine) AudioSystem.getLine(info);
        line.open(stream.getFormat());
        line.start();        // Continuously read and play chunks of audio
        int numRead = 0;
        byte[] buf = new byte[line.getBufferSize()];
        while ((numRead = stream.read(buf, 0, buf.length)) >= 0) {
            int offset = 0;
            while (offset < numRead) {
                offset += line.write(buf, offset, numRead-offset);
            }
        }
        line.drain();
        line.stop();
        stream.close();
    } catch (MalformedURLException e) {
      e.printStackTrace();
    } catch (IOException e) {
      e.printStackTrace();
    } catch (LineUnavailableException e) {
      e.printStackTrace();
    } catch (UnsupportedAudioFileException e) {
      e.printStackTrace();
    }  }
}
