A thread\'s run() method includes the following lines:

try {

sleep(100);

} catch (InterruptedException e) { }

Assuming the thread is not interrupted, which one of the

following statements is correct?

A)The code will not compile, because exceptions may not

be caught in a thread\'s method.

B)At line 2, the thread will stop running. Execution will

resume in, at most, 100 milliseconds.

At line 2, the thread will stop running. It will resume

running in exactly 100 milliseconds.

D)At line 2, the thread will stop running. It will resume

running some time after 100 milliseconds have elapsed.
