How do I resolve issues with Java libraries?

I'm having trouble with a Java library. It keeps throwing exceptions. What should I do?

First, can you provide the specific exception message you're encountering? That will help narrow down the issue.

It's throwing a NullPointerException when I try to access a method.

A NullPointerException usually means you're trying to use an object that hasn't been initialized. Check if the object is null before calling the method.

I checked, and it seems like the object is indeed null. How do I fix that?

You need to ensure that the object is properly instantiated before you use it. Look for the part of your code where the object is created.
