Using a non-static variable in a static method JAVA

Question

So I am writing a very large java code, within this code I want it to output files in a particular file format. In this instance it is going to be a simple .txt file.

Answer 1

you should know non-static method belongs to Object ,but static method belongs to Class.Therefore the getNonStaticVariables method and nonStaticVariable should be static or change the outputToTxt to non-static.
