What are the differences between atomic classes and synchronized classes?

Can you explain the differences between atomic classes and synchronized classes?

Sure! Atomic classes are designed for thread-safe operations without using synchronization, while synchronized classes use locks to control access to methods or blocks.

What are some examples of atomic classes?

Examples of atomic classes include AtomicInteger, AtomicBoolean, and AtomicReference, which provide atomic operations on single variables.

When should I use synchronized classes instead of atomic classes?

Use synchronized classes when you need to manage complex operations involving multiple variables or when atomic classes don't provide the required functionality.

Are there performance differences between the two?

Yes, atomic classes generally offer better performance due to reduced overhead from avoiding locks, making them preferable for simple operations.
