How do I troubleshoot issues in Go and Java applications?

I'm having trouble with my Go application crashing unexpectedly. What should I do?

First, check the error logs for any panic messages. You can also run your application with the -race flag to detect race conditions.

I did that, and it seems like there's a nil pointer dereference. How can I fix it?

A nil pointer dereference usually means you're trying to access a method or property on a nil object. Make sure to initialize your variables properly before use.

What about my Java application? It's throwing a NullPointerException.

In Java, a NullPointerException occurs when you try to use an object reference that has not been initialized. Check your object assignments and ensure they are not null before accessing them.
