238. Which two code fragments will execute the method doStuff() in a separate thread? (Choose two.) (A) (B) (C) (D) (E) (F)

225. Given: 10. Runnable r = new Runnable(){ 11. public void run(){ 12. try{ 13. Thread.sleep(1000)； 14. }catch(InterruptedException e){ 15. System.out.println("interrupted")； 16. } 17. System.out.println("ran")； 18. } 19. }； 20. Thread t = new Thread(r)； 21. t.start()； 22. System.out.println("started")； 23. t.sleep(2000): 24. System.out.println("interrupting")； 25. t.interrupt()； 26. System.out.println("ended")； Assume that sleep(n) executes in exactly n milliseconds. and all other code executes in an insignificant amount of time. Place the fragments in the output area to show the result of running this code.

228. Which three will compile and run without exception? (Choose three.) (A) private synchronized Object o； (B)(C) public synchronized void go(){/* code here */} (D) private synchronized(this) void go(){/* code here */} (E) (F)

236. Given: 1. class Computation extends Thread{ 2. 3. private int num； 4. private boolean isComplete； 5. private int result； 6. 7. public Computation(int num){this.num = num；} 8. 9. public synchronized void run(){ 10. result = num * 2； 11. isComplete = true； 12. notify()； 13. } 14. 15. public synchronized int getResult(){ 16. while(!isComplete){ 17. try{ 18. wait()； 19. }catch(InterruptedException e){} 20. } 21. return result； 22. } 23. 24.public static void main(String[] args){  25. Computation[] computations = new Computation[4]； 26. for(int i=0； i＜computations.length； i++){ 27. computations[i] = new Computation(i)； 28. computations[i].start()； 29. } 30. for(Computation c : computations) 31. System.out.print(c.getResult() + " ")； 32. } 33. } What is the result? (A) The code will deadlock. (B) The code may run with no output. (C) An exception is thrown at runtime. (D) The code may run with output "0 6". (E) The code may run with output "2 0 6 4". (F) The code may run with output "0 2 4 6".

237. Place the code elements into the class so that the code compiles and prints "Run. Run. doIt. " in exactly that order. Note that there may be more than one correct solution. 

240. Place a Class on each method that is declared in the class.
