How do I synchronize threads in programming?

To synchronize threads, you can use mechanisms like mutexes, semaphores, or monitors. What programming language are you using?

I'm using Java. Can you give me an example?

Sure! In Java, you can use the synchronized keyword to control access to a method or block. Here's a simple example:

public synchronized void myMethod() {
    // critical section code
}

What happens if multiple threads try to access the synchronized method?

If multiple threads attempt to access a synchronized method, only one thread can execute it at a time. Other threads will be blocked until the method is free.

Are there any performance issues with using synchronization?

Yes, excessive synchronization can lead to performance bottlenecks, as it may cause threads to wait longer than necessary. It's important to use it judiciously.
