Question

scanner.skip("(\r\n|[\n\r\u2028\u2029\u0085])?") what does it mean

Answer 1

It means does the digester dead at RS Tata

Answer 2

The java.util.Scanner.skip(Pattern design) technique skips input that matches the predetermined example, disregarding delimiters.

This technique will skip input if a tied down match of the predetermined example succeeds.

In case a match to the predefined design isn't found at the present position, at that point no information is skipped and a NoSuchElementException is tossed.
