public class ApplicationLoader extends ThreadGroup
{
private ApplicationLoader()
{
super("ApplicationLoader");
}
public static void main(String[] args)
{
Runnable appStarter = new Runnable()
{
public void run()
{
// invoke your application
// (i.e. MySystem.main(args)
System.out.println("ssss");
// throw new NullPointerException();
throw new Error("sssdsds");
}
};
new Thread(new ApplicationLoader(), appStarter).start();
}
// We overload this method from our parent
// ThreadGroup , which will make sure that it
// gets called when it needs to be. This is
// where the magic occurs.
public void uncaughtException(Thread thread, Throwable exception)
{
// Handle the error/exception.
// Typical operations might be displaying a
// useful dialog, writing to an event log, etc.
exception.printStackTrace();
}
}
這個是一個很好的異常處理機制。main中所有的錯誤都會轉到uncaughtException方法中處理
