ReadWriteLock was added after J2SE 1.5.
If I use the latest version(J2Se1.6), then may I use ReadWriteLock of java.util.concurrent.locks ?
Of cource, I never use it in Lock/Unlock Method.

I want to use it in read/update/create/delete.

Hi,

it's part of the standard API so yes.

Why can't you use it in lock/unlock?

ReadWriteLock and all the concurrent lock stuff were added in 5.0, not 6.0, so yes, that's perfectly valid.

sure. I am using it - it is easy and nice
This is also very easy to keep trace of threads waiting for the particular row.
