Why Synchronization Is Needed in Multi-Threading Applications?
Synchronization Technique - Lock and Synchronized Code
"synchronized" - How Java Supports Synchronization
BankingThread.java - Synchronization Sample Program
BankingThread.java - Synchronization Sample Program Output
- Synchronization is needed in a multi-threading application to ensure that one thread is updating
a shared data other threads wait and get the updated value.
- Synchronization uses a lock to represent the shared data to allow each thread to use the lock status
to Synchronize with each other.
- Synchronization code block is a unit of code in a thread that requires synchronization on a particular lock.
- More synchronization locks or longer synchronization code blocks slow down application performance.
