Your system is not "running" some other "file", not in the sense that
you think. Your Java source files are compiled into .class files, these
are loaded up into memory as required, and broadly speaking it's the
bytecodes in these class files that get executed ("run"). The first
application code to execute is the proper main() method in your main
class...like Nvj5.main(). Since you are using standard library code
also, like FileInputStream, code in those classes - and in the classes
that FileInputStream uses, and so on and so on - also gets executed.
That mysterious huge file is a standard library class that your code
needs to work. It's not irrelevant. A high percentage of the time when
you write buggy code the errors start in library code, not in your own
code. You need to look at the entire stack. You will notice that
somewhere in the stack are line references to your own code also.
You deleted and renamed *which* files exactly? Also, you have a class
Nvj5 but a corresponding source file "Nvj5.java". You'll find that
people understand you better if you differentiate between data files
(like NVRAM.TXT) and source files (like Nvj5.java).
Are you saying that you renamed class Nvj5 in source file Nvj5.java to
class Pwll12 in source file Pwll12.java, say, and ever since your
program has run like a charm? That seems highly unlikely. In fact that's
astronomically unlikely.
What IDE or programming text editor are you using? How many "main"
classes are currently available in your workspace? When you tried that
failing run did you see any console output at all?
