My query is related to code shown below. Here I have declared a few variables, like JFrame, JTextArea as instance variables where as a few, like JPanel and JButton, as local variables inside method go(). I could also have made all the variables as instance variables or all of these as local variables... It would work fine. Now my question is what is a better coding practice? How and where will this make a difference.
I am sorry if this question sounds very stupid, I am still new to programming. Thank you all!
Generally, I would move all variables into a method that you don't need to use outside of that method. They just clutter up the namespace (using another field called "frame" anywhere else in the program might become confusing), and the objects they're pointing to might not become eligible for garbage collection.
