第225題

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.

答案：
Output

(no more output)
started
ran
interrupting
ended

參考：13-3 Runnable介面

---------------------------------

23. 主執行緒 睡2秒, 副執行緒稅1秒, 所以先印出ran 再印 interrupt.
