Sample24 is run - what will be the output?
public class Sample24 implements Runnable
{
public void run() throws InterruptedException
{
Thread.sleep(100);
}
public static void main(String[] args)
{
new Thread(new Sample24()).start();
}
}
Answer: D
Runnable declares run() with no throws clause, and an override may not add a checked exception to the method it implements. The sleep therefore has to be wrapped in a try-catch inside run(). Runnable declares only run(); start() belongs to Thread.
