Hi All,
I am having a small doubt in Threads. In my application, I am creating a ArryList in ClassA, adding 100 different values. Now I am passing this ArrayList to ClassB. Here, creating 'n' number of threads. All the threads are making some chages on the same ArrayList. If one thread made any changes, It should reflect to another.
Can any one Help me for this condition. Thanks.
Regards,
Prabhakaran

Try Vector Instead of ArrayList

To expand on what Siva Arun said, that sounds like a synchronisation problem, that changes are made at the same time by your many threads.
