What is the difference between closing a resource and making the scanner private in java?

Question

private static Scanner sc;

&

sc.close();

What is the difference between these two things?

Your question is unclear. "private static Scanner sc;" declares a "Scanner" variable ... but leaves "sc" uninitialized. "sc.close();" closes a scanner object. I havwe no idea what the heck you mean by "&". IMPORTANT POINT: closing a scanner linked to System.in will close System.in itself: https://stackoverflow.com/questions/14142853/close-a-scanner-linked-to-system-in — paulsm4, Jan 04 '21 at 04:27

These two concepts are unrelated. According to the Java documentation:

The private modifier specifies that the member can only be accessed in its own class.

See this thread to learn about Scanner.close().

you're correct - but it sounds like the OP is deeply confused about more than just "scope" or the "close()" method. – paulsm4 Jan 04 '21 at 04:30
Fair enough, should I remove this answer or keep it for future visitors? – Adrian Russo Jan 04 '21 at 04:31
