Write thread connection pool code in java

The code for writing a thread connection pool in java is as follows:

1. Thread Pool:
2. Import java. util. Collections list;
4. Public abstract class Manager {
6. Private String mThreadPoolName = null;
8. Private int mThreadPoolMaxSize = 1;
10. Private worker list workers = new worker list ();
12. Public Manager (){
13. }
15. Public Manager (String name, int poolMaxSize ){
16. MThreadPoolName = name;
17. CreateWorker (name, poolMaxSize );
18. MThreadPoolMaxSize = poolMaxSize;
19. }
21. Private void createWorker (int poolMaxSize ){
22. For (int I = 0; I <poolMaxSize; I ){
23. Worker worker = new... Worker (this );
24. Workers. addLast (worker );
25. }
26. }
28. Public synchronized Worker getIdleWorker (){
29. Return (Worker) workers. removeFirst ();
30. }
32. Public synchronized void policyfree (Worker worker ){
33. If (workers. size () <mThreadPoolMaxSize ){
34. Workers. addLast (worker );
35. } Else {
36. Worker = null;
37. }
38. }
40. Public int getThreadPoolMaxSize (){
41. Return mThreadPoolMaxSize;
42. }
44. Public void setThreadPoolMaxSize (int threadPoolMaxSize ){
45. This. mThreadPoolMaxSize = threadPoolMaxSize;
46. }
47. }
49. Thread abstract class
50. Public abstract class Worker implements Runnable {
52. Private Manager mManager = null;
54. Private Thread mThread = null;
56. Public Worker (){
57. }
59. Public Worker (String threadName, Manager manager ){
60. MManager = manager;
61. MThread = new Thread (this, threadName );
62. Init ();
63. & Nb
