What is synchronization in Java concurrency?

What is synchronization in Java concurrency?

Synchronization in Java concurrency is a mechanism that ensures that two or more concurrent threads do not simultaneously execute specific sections of code, preventing data inconsistency.

Why is synchronization important in multi-threading?

Synchronization is crucial in multi-threading to avoid race conditions, where multiple threads access shared resources simultaneously, leading to unpredictable results.

How can I implement synchronization in Java?

You can implement synchronization in Java using the synchronized keyword, which can be applied to methods or blocks of code to control access.

Can you give an example of synchronized methods?

Sure! Here's a simple example:

public synchronized void increment() {
    this.count++;
}

This method ensures that only one thread can execute it at a time.

What are the drawbacks of using synchronization?

The main drawbacks include potential performance bottlenecks due to thread contention and the risk of deadlocks if not managed properly.
