In what situations is it preferable to use synchronized methods in programming?

Synchronized methods in Java are used when it is necessary to ensure correct access to shared resources from multiple threads, to avoid race conditions and ensure data integrity.

It is preferable to use synchronized:

• When working with mutable shared variables or collections.
• When it is necessary to guarantee that only one thread executes a specific block of code at a time.
• To implement critical sections where it is important to prevent concurrent access.

For example, if you have a counter that is incremented from different threads, the increment method should be synchronized to avoid errors.
