What are some examples of synchronization in Java?

In Java, synchronization is used to control access to shared resources. One common example is using the synchronized keyword in methods.

Can you give me a code example of a synchronized method?

Sure! Here's a simple example:

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

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

What about using synchronized blocks?

Synchronized blocks allow more granular control. For example:

synchronized(this) {
    // critical section code
}

This only locks the block, not the entire method.

Are there any alternatives to synchronization?

Yes, you can use java.util.concurrent package classes like ReentrantLock for more flexibility.
