What is the difference between deadlock and livelock in Java?

What is the difference between deadlock and livelock in Java?

Deadlock occurs when two or more threads are blocked forever, waiting for each other. Livelock, on the other hand, happens when threads keep changing states in response to each other without making progress.

Can you give me an example of each?

Sure! In a deadlock, Thread A holds Resource 1 and waits for Resource 2, while Thread B holds Resource 2 and waits for Resource 1. In a livelock, two threads might keep releasing and requesting resources in a way that they never proceed.

How can I prevent deadlocks in my Java application?

You can prevent deadlocks by using a timeout for resource requests, acquiring resources in a consistent order, or using deadlock detection algorithms.

What tools can help me detect deadlocks in Java?

Tools like VisualVM, JConsole, and Java Mission Control can help you monitor and detect deadlocks in your Java applications.
