Synchronized vs ReadWriteLock vs StampedLock [Java Multithreading]
We analyze what to do when you need to work with multithreading. Synchronized is certainly a classic, but maybe there are solutions that are better in terms of performance? Alexey Konokhov, senior java engineer will consider alternatives.
