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 use synchronized blocks instead of synchronized methods?

Synchronized blocks allow for more granular control over synchronization, enabling you to lock only specific parts of your code rather than the entire method.

Can you give me an example of a synchronized block?

Sure! Here's a simple example:

synchronized(this) {
    // critical section code
}
``` This locks the current object, allowing only one thread to execute the code inside the block.

What happens if a thread is blocked on a synchronized block?

If a thread is blocked on a synchronized block, it will wait until the block is released by the thread currently executing it, which can lead to potential deadlocks if not managed properly.
