I am creating gui calculator in Java
I am using IDEA
programme runs successfully but it shows an error that Field ‘(any field)’ may be ‘final’……
I don’t know what it is
It’s a warning/information message telling you that these variables are better to be declared as
final. Whenever your IDE finds cases where you have not assigned anything to a variable, except at the time of initialization, it may give you such a warning/information message so that you can consider adjusting the code if required. I believe, you already understand the concept of the keyword,
final in Java.
