Which of the following is a disadvantage of creating a class by extending Thread rather than implementing Runnable?

By extending Thread we can't inherit any other classes, while with Runnable we still can inherit another class.

We have to call the start method on the object to create a thread rather than the run method

By extending the thread class, we must overwrite the thread pool method and run method rather than just the run method.

Extending Thread is used in legacy pre$-$Java $5$ code, while implementing Runnable is more modern.
