我有class PlayTone ，其中有Thread张MP3张Library来自jLayer public static class PlayTone extends Thread{
public void run() {
while (true) {
try {
FileInputStream fis = new FileInputStream(jLabel12.getText());
Player playMP3 = new Player(fis);
playMP3.play();
} catch (Exception e) {
System.out.println("PLAY TONE");
//e.printStackTrace();
}
}
}
}
}。
public class PlayAlarmWhenTheTimeIsRight extends Thread {
private volatile boolean running = true;
final playTOne pt = new playTOne();
String textsOfAllLabels = jLabel4.getText() + jLabel7.getText() + " " + jLabel8.getText();
String first = textsOfAllLabels.substring(0, 5);
String second = textsOfAllLabels.substring(6, 9);
final String ifTime = first + second;
public void run() {
while (running) {
if (ifTime.contains(jLabel11.getText())) {
pt.start();
} else if(jButton4.isEnabled()==false){
System.out.println("shutodown");
shutdownThisThread();
}else{
}
}
}
public void shutdownThisThread() {
running = false;
}
}
我还有另外一个类叫上面的 PlayTone 类。下面你可以看到那个班级
Throws但是当我运行此程序时Exception和 Exception in thread "Thread-7" java.lang.IllegalThreadStateException
at java.lang.Thread.start(Thread.java:705)
at AlarmClock$PlayAlarmWhenTheTimeIsRight.run(AlarmClock.java:675)
如下。
USE Sunset
GO
ALTER VIEW vedere1 AS
SELECT DISTINCT c.Nume AS num_client, r.Nr_camera AS camera,
f.Data_emiterii, f.Suma
FROM factura f, clienti c, camera r
WHERE (f.Id_client=c.Id_client) AND (r.Id_client=c.Id_client)
GO
任何人都可以告诉我我的代码有什么问题???
