Question 1: Given that Triangle implements Runnable, and:
31. void go() throws Exception {
32. Thread t = new Thread(new Triangle());
33. t.start();
34. for(int x = 1; x < 100000; x++) {
35. //insert code here
36. if(x%100 == 0) System.out.print("g");
37. } }
38. public void run() {
39. try {
40. for(int x = 1; x < 100000; x++) {
41. // insert the same code here
42. if(x%100 == 0) System.out.print("t");
43. }
44. } catch (Exception e) { }
45. }
Which one statement, inserted independently at both lines 35 and 41, tend to allow both threads to
temporarily pause and allow the other thread to execute?

1. Thread.wait();
2. Thread.join();
3. Thread.yield();
4. Thread.notify();
