What are threading deadlocks and how can they be resolved?

Threading deadlocks occur when two or more threads are blocked forever, each waiting on the other to release a resource. To resolve them, you can use techniques like timeout, resource ordering, or deadlock detection algorithms.

Can you give me an example of a deadlock situation?

Sure! Imagine two threads: Thread A holds Resource 1 and needs Resource 2 to proceed, while Thread B holds Resource 2 and needs Resource 1. Neither can continue, resulting in a deadlock.

How can I prevent deadlocks in my application?

You can prevent deadlocks by ensuring that all threads acquire resources in a consistent order, using timeouts, or implementing a deadlock detection mechanism that can recover from such situations.

What tools can help me detect deadlocks?

There are several tools available, such as VisualVM, JConsole, and specific logging frameworks that can help you monitor thread states and detect deadlocks in your application.
