Reading a character input in the console using the Scanner Class in Java

Question

I am trying to read a character input at the console using the Scanner class, by creating a scanner object. I used two commands:

1. char ch = sc.next(".").charAt(0);
2. char ch = sc.next().charAt(0); I've tried both and both work well, but what's the difference between the two commands? What does the "." in the first command stand for?

Answer 1

This method Finds and returns the next complete token from this scanner. A complete token is preceded and followed by input that matches the delimiter pattern.

char ch = sc.next(".").charAt(0);

In this code it waiting to match this from this input "."
