Need Fool Proof Synchronization of ArrayList in A Multi-threaded Environment

Question

I\'ve been at this for a week now doing my research on how to properly synchronize an ArrayList.

My main issue in a nutshell is I have a \"master\" ArrayList of objects.

Answer 1

Another approach is to protect all access to the list, but with a ReadWriteLock instead of synchronized blocks.

This allows simultaneous reads in a safe manner, and could improve performance a lot in a scenario with many reads and few writes.
