Achieve strong performance with threads, Part 2 Developers sometimes create multithreaded programs that produce erroneous values or exhibit other strange behaviors. Odd behavior typically arises when a multithreaded program does not use synchronization to serialize thread access to critical code sections. What does it mean to serialize thread access to critical code sections? This article explains Java's synchronization mechanism, and two problems that arise when developers fail to use that mechanism correctly.   |
