Sample09 is run - what will be the output?
public class Sample09
{
static void report()
{
System.out.print(Thread.currentThread().isInterrupted() + " ");
}
public static void main(String[] args)
{
Thread.currentThread().interrupt();
report();
report();
}
}
Answer: A
isInterrupted() reports the status without changing it, so both calls answer true and the flag is still set afterwards. Swapping it for the static Thread.interrupted() would give true then false, which is the trap this pair of questions exists to separate.
