How can I prevent deadlocks in Java threading?

To prevent deadlocks in Java, you can follow several strategies such as avoiding nested locks, using a timeout for lock attempts, and ensuring a consistent lock order.

What is a nested lock?

A nested lock occurs when a thread holds a lock and tries to acquire another lock that is already held by another thread, potentially leading to a deadlock.

Can you give an example of a deadlock situation?

Sure! A classic example is when Thread A holds Lock 1 and waits for Lock 2, while Thread B holds Lock 2 and waits for Lock 1. This creates a deadlock.

How can I detect deadlocks in my application?

You can use tools like Java VisualVM or thread dumps to analyze thread states and identify deadlocks in your application.
