QUESTION 3 Given: 7. void waitForSignal() { 8. Object obj = new Object(); 9. synchronized (Thread.currentThread()) { 10. obj.wait(); 11. obj.notify(); 12. } 13. } Which statement is true? A. This code can throw an InterruptedException. B. This code can throw an IllegalMonitorStateException. C. This code can throw a TimeoutException after ten minutes. D. Reversing the order of obj.wait() and obj.notify() might cause this method to complete normally. E. A call to notify() or notifyAll() from another thread might cause this method to complete normally. F. This code does NOT compile unless "obj.wait()" is replaced with "((Thread) obj).wait()".
Which two statements are true? (Choose two.) A. It is possible for more than two threads to deadlock at once. B. The JVM implementation guarantees that multiple threads cannot enter into a deadlocked state. C. Deadlocked threads release once their sleep() method's sleep duration has expired. D. Deadlocking can occur only when the wait(), notify(), and notifyAll() methods are used incorrectly. E. It is possible for a single-threaded application to deadlock if synchronized blocks are used incorrectly. F. If a piece of code is capable of deadlocking, you cannot eliminate the possibility of deadlocking by inserting invocations of Thread.yield().
