Question 126

Given:

Which one is correct?

    Correct Answer: A

    In Java, once a thread has been started and completes its execution, it cannot be restarted. Attempting to restart a thread by calling its start() method again will throw an IllegalThreadStateException. In the given code, the thread 't1' is started twice, which leads to an IllegalThreadStateException at runtime, making option A the correct answer.
