What is thread synchronization in Java?

What is thread synchronization in Java?

Thread synchronization in Java is a mechanism that ensures that two or more concurrent threads do not simultaneously execute some particular program segment, which can lead to data inconsistency.

Why is synchronization important in multithreading?

Synchronization is crucial in multithreading to prevent thread interference and memory consistency errors, ensuring that shared resources are accessed in a controlled manner.

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 restrict access to a resource.

What are the different types of locks in Java?

Java provides several types of locks, including intrinsic locks (using synchronized), explicit locks (using ReentrantLock), and read/write locks.

Can you give an example of synchronized methods?

Sure! Here's a simple example:

class Counter {
    private int count = 0;

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

    public synchronized int getCount() {
        return count;
    }
}
