What is lock-based synchronization and when should I use it?
Lock-based synchronization is a method to control access to shared resources in concurrent programming. You should use it when multiple threads need to access shared data to prevent race conditions.
Can you give me an example of a situation where it's necessary?
Sure! If you have a banking application where multiple threads are updating account balances, using locks ensures that one thread's update doesn't interfere with another's.
Are there any downsides to using lock-based synchronization?
Yes, it can lead to issues like deadlocks, where two or more threads are waiting on each other to release locks, causing the program to hang.
How can I avoid deadlocks when using locks?
You can avoid deadlocks by ensuring that all threads acquire locks in a consistent order or by using timeout mechanisms.
