Multithread y, policyall, and wait practices

 

 

1. Package com. Rx;
3. Class mythread_1 extends thread
4. {
5. Object lock;
7. Public mythread_1 (Object O)
8. {
9. Lock = O;
10. }
12. Public void run ()
13. {
14. Try
15. {
16. Synchronized (LOCK)
17. {
18. System. Out. println ("Enter thread_1 and wait ");
19. Lock. Wait ();
20. // Lock. Wait (12222 );
21. System. Out. println ("be notified ");
22. }
23. } Catch (interruptedexception e ){
24. System. Out. println ("exce ");
25. }
26. }
27. }
29. Class mythread_2 extends thread
30. {
31. Object lock;
33. Public mythread_2 (Object O)
34. {
35. Lock = O;
36. }
38. Public void run ()
39. {
40. Synchronized (LOCK)
41. {
42. System. Out. println ("Enter thread_2 and to define y ");
43. Lock. Policy ();
44. // Lock. policyall ();
45. }
46. }
47. }
50. Public class mythread
51. {
52. Public static void main (string [] ARGs) throws interruptedexception
53. {
54. // Int [] In = new int [0]; // notice
55. Object in = new object ();
56. Mythread_1 T1 = new mythread_1 (in );
57. Mythread_2 t2 = new mythread_2 (in );
59. // Mythread_1 t13 = new mythread_1 (in );
60. T1.start ();
61. // Thread. Sleep (12222 );
62. // T13.start ();
63. T2.start ();
64. }
65. }

The running result is as follows:

1. Enter thread_1 and wait
2. Enter thread_2 and to sort y
3. Be notified

Run the policyall instance test:

1. Package com. Rx;
3. Class mythread_1 extends thread
4. {
5. Object lock;
7. Public mythread_1 (Object O)
8. {
9. Lock = O;
10. }
12. Public void run ()
13. {
14. Try
15. {
16. Synchronized (LOCK)
17. {
18. System. Out. println ("Enter thread_1 and wait ");
19. Lock. Wait ();
20. // Lock. Wait (12222 );
21. System. Out. println ("be notified ");
22. }
23. } Catch (interruptedexception e ){
24. System. Out. println ("exce ");
25. }
26. }
27. }
29. Class mythread_2 extends thread
30. {
31. Object lock;
33. Public mythread_2 (Object O)
34. {
35. Lock = O;
36. }
38. Public void run ()
39. {
40. Synchronized (LOCK)
41. {
42. System. Out. println ("Enter thread_2 and to define y ");
43. // Lock. Y ();
44. Lock. policyall ();
45. }
46. }
47. }
50. Public class mythread
51. {
52. Public static void main (string [] ARGs) throws interruptedexception
53. {
54. // Int [] In = new int [0]; // notice
55. Object in = new object ();
56. Mythread_1 T1 = new mythread_1 (in );
57. Mythread_2 t2 = new mythread_2 (in );
59. Mythread_1 t13 = new mythread_1 (in );
60. T1.start ();
61. // Thread. Sleep (12222 );
62. T13.start ();
63. T2.start ();
64. }
65. }

The running result is as follows:

1. Enter thread_1 and wait
2. Enter thread_1 and wait
3. Enter thread_2 and to sort y
4. Be notified
5. Be notified

 

1. Package com. Rx;
3. Class mythread_1 extends thread
4. {
5. Object lock;
7. Public mythread_1 (Object O)
8. {
9. Lock = O;
10. }
12. Public void run ()
13. {
14. Try
15. {
16. Synchronized (LOCK)
17. {
18. System. Out. println ("Enter thread_1 and wait ");
19. // Lock. Wait ();
20. Lock. Wait (10 );
21. System. Out. println ("be notified ");
22. }
23. } Catch (interruptedexception e ){
24. System. Out. println ("exce ");
25. }
26. }
27. }
29. Class mythread_2 extends thread
30. {
31. Object lock;
33. Public mythread_2 (Object O)
34. {
35. Lock = O;
36. }
38. Public void run ()
39. {
40. Synchronized (LOCK)
41. {
42. System. Out. println ("Enter thread_2 and to define y ");
43. // Lock. Y ();
44. Lock. policyall ();
45. }
46. }
47. }
50. Public class mythread
51. {
52. Public static void main (string [] ARGs) throws interruptedexception
53. {
54. // Int [] In = new int [0]; // notice
55. Object in = new object ();
56. Mythread_1 T1 = new mythread_1 (in );
57. Mythread_2 t2 = new mythread_2 (in );
59. // Mythread_1 t13 = new mythread_1 (in );
60. T1.start ();
61. Thread. Sleep (1000 );
62. // T13.start ();
63. T2.start ();
64. }
65. }

The running result is as follows:

1. Enter thread_1 and wait
2. Be notified
3. Enter thread_2 and to sort y

 

Test it on your own in other cases.
