What is Java synchronization and why is it important?

What is Java synchronization and why is it important?

Java synchronization is a mechanism that ensures that two or more concurrent threads do not simultaneously execute some particular program segment. It's important for preventing thread interference and ensuring data consistency.

Can you explain how to implement synchronization in Java?

You can implement synchronization in Java using the synchronized keyword. This can be applied to methods or blocks of code to control access by multiple threads.

What are the different types of synchronization in Java?

There are two main types of synchronization in Java: intrinsic (or monitor) synchronization, which uses the synchronized keyword, and explicit synchronization, which uses classes from the java.util.concurrent package.

What are some common pitfalls when using synchronization?

Common pitfalls include deadlocks, where two or more threads are waiting indefinitely for each other to release locks, and performance issues due to excessive locking.
