What are synchronized blocks in Java?

What are synchronized blocks in Java?

Synchronized blocks in Java are used to control access to a block of code by multiple threads, ensuring that only one thread can execute it at a time.

Why would I need to use synchronized blocks?

You would use synchronized blocks to prevent thread interference and ensure data consistency when multiple threads access shared resources.

Can you show me an example of a synchronized block?

Sure! Here's a simple example:

public void exampleMethod() {
    synchronized(this) {
        // critical section code
    }
}

What happens if I don't use synchronized blocks?

If you don't use synchronized blocks, you may encounter issues like race conditions, where the outcome depends on the timing of thread execution.
