问题:
5. class Order2 implements Runnable {
6. public void run() {
7. for(int x = 0; x 〈 4; x++) {
8. try { Thread.sleep(100); } catch (Exception e) { }
9. System.out.print("r");
10. } }
11. public static void main(String [] args) {
12. Thread t = new Thread(new Order2());
13. t.start();
14. for(int x = 0; x 〈 4; x++) {
15. // insert code here
16. System.out.print("m");
17. } } }
哪一个插入到第15行,最有可能产生输出 rmrmrmrm ?()
A . Thread.sleep(1);
B . Thread.sleep(100);
C . Thread.sleep(1000);
D . try { Thread.sleep(100); } catch (Exception e) { }
