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
myObject
being initialized? - CodeSleuth: Are you sure
myObject
isn'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 seems like you might not be initializing myObject
properly before calling the sayHello()
method. Make sure you initialize it using the new
keyword before calling any methods on it.

new
keyword in one of the branches of my code. Problem solved!

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!
