How can I pass an exception from one thread to another thread

Question

If I create a new class, that will extends the class Thread, the methode run() can not be use with the statement Throws Exeption .
The question now: Is there any possibility to pass an exception from one thread to another thread?
Thx.

It really depends on what you want to do with your exception. Is there some sort of global handler that will process the exceptions in some meaningful way? Unless you have that, there's not much point in throwing an exception in a thread, unless you simply want the stack trace generated.
Presuming that you have a global handler that can catch exceptions, nest your Exception subclass inside a RuntimeException:
public class NestedRuntimeException extends RuntimeException
    private final m_nestedException;
    public NestedRuntimeException(final Exception originalException)
        super("An exception occurred with message: " + originalException.getMessage());
        m_nestedException;
    public Exception getNestedException()
        return m_nestedException;
}Your global handler can catch the NestedRuntimeException or be supplied it to process by the thread group.
