Java: Synchronized and Locks
Answer
It serializes access to shared resources by locking.
Race conditions occur when multiple threads access shared data simultaneously, leading to inconsistent results. The 'synchronized' keyword ensures that only one thread at a time can execute a particular block of code or method, effectively serializing access to shared resources and preventing race conditions. In a flash sale system, using 'synchronized' on inventory update ensures each update is atomic.
