Java Synchronized vs Locks

What is the difference between synchronized methods and locks in Java?

Synchronized methods are a simpler way to control access to a method by a single thread, while locks provide more flexibility and control.

Can you explain how to use ReentrantLock?

Sure! ReentrantLock allows you to lock a section of code and provides methods for fairness and interruptibility.

When should I use synchronized over locks?

Use synchronized for simpler scenarios where you need basic thread safety, and locks for more complex situations requiring advanced features.

Are there performance differences between them?

Yes, locks can be more performant in high contention scenarios, but synchronized methods are easier to use and understand.
