What is the disadvantage of subclassing the Thread class? [Check all correct answers]
1. You cannot subclass another class.
2. You can only subclass one class.
3. The Thread runs in another JVM.


Answer: 1,2
According to the given senario, if we subclass Thread, then we cant extend any other class. Can anyone explain how 2 is also the right answer?
Thanks.

Thanks Jo. Even I thought the wording was vague. I just needed a second opinion.

2. You can only subclass one class.


This option is not a disadvantage of sub classing a Thread. I would not choose 2. I think Dan should change the wording in the option or remove 2 from the answer list.

This question is from javacertificate.com. This is not one of Dan's.
Thanks.

Hey,
2. You can only subclass one class.

actually means you can subclass only the Thread class and no other class.
Kind regards,

I think option '2' has no relation with the question. So it should not be part of the 'right answer'.

My first bit of advice is that if you are going to be a mime, you shouldn't talk. Even the tiny ad is nodding:
