Question
Why is my Java program crashing on this line?
I keep getting a NullPointerException
I checked if myObject is null but it's not
Comments on question:
- JavaMaster: Can you provide more context to your code? How is
myObjectbeing initialized? - CodeSleuth: Are you sure
myObjectisn't null? Try printing its value right before callingsayHello(). - DebugDiva: It's possible that the NullPointerException is occurring within the
sayHello()method. Can you share that code too? - QuestionAsker: @JavaMaster Here's how I'm initializing
myObject:MyClass myObject;and latermyObject = new MyClass();

It's possible that the NullPointerException is occurring inside the sayHello() method. Please share the code of the sayHello() method, so we can help you pinpoint the issue.

- QuestionAsker: I checked the
sayHello()method, but there's no issue there. It was actually a problem with my initialization, like the other answer mentioned. Thanks for the suggestion, though!
